Now your new CAR knows if you've put on weight! Volvo adds body measuring sensors to seatbelts

If you've put on a few pounds recently, even your new car will soon know about it.
That's because Volvo has today revealed it has reinvented a 65-year-old vehicle safety feature - and it now includes body measuring technology designed to mitigate the risk of injury during crashes.
The Swedish car brand - majority owned by China's Geely and synonymous with safety - has today unveiled its new 'super seatbelt' aimed to improve protection levels in its latest models.
The new 'multi-adaptive safety belt' is an evolution of the three-point seatbelts that have been used in cars since 1959, which Volvo engineer Nils Bohlin originally created.
What differentiates the new super belt is the inclusion of sensors that analyse the height, weight, body shape and seating position of an individual.
This information - along with other sensors that measure the scale of the impact when there is a collision - in a split second calculates the optimum pressure and where load is spread across the body to provide the highest level of protection.
Volvo said the new seatbelt tech has the capacity to help 'save millions more lives' by providing bespoke protection for every occupant.
While conventional three-point seatbelt in cars currently provide only three 'load-limiting profiles', the new system has an endless number of adjustments that tailor to the crash scenario and person inside the vehicle.
In essence, a larger passenger will receive a more powerful belt load to keep their body restrained during a crash to reduce the risk of head trauma.
Whereas smaller, lighter individuals will have a lower belt load applied to avoid injuries that can be sustained from a conventional seat belt that often overpowers their frames, especially around their ribs.
The system adjusts each time you sit in the seat, so your car will know if you've put on a bit of weight of late.
For those of us actively avoiding the bathroom scales of late, don't worry, it won't be used for fat shaming - instead, the information is only utilised to better protect drivers and passengers.

The seatbelt, which has been co-developed with ZF Lifetech, also utilises sensors that gather data about the force and nature a collision.
This information is processed 'in less than a blink of an eye' to determine the precise amount of force the belt needs to apply for the person in each of the seats based on their unique body profiles, the intensity of the collision and where they are sitting in the car in relation to where the impact is felt.
The brand says: 'The system analyses the unique characteristics of a crash – such as direction, speed, and passenger posture – and shares that information with the safety belt.
'Based on this data, the system selects the most appropriate setting,' it explained.
The new multi-adaptive safety belt will be installed in the new electric EX60 on sale next year. Other models in Volvo's line-up (like the EX90 pictured) are likely to get the technology when they're updated and facelifted mid production cycle
And Volvo isn't just developing this technology as a concept - the multi-adaptive safety belt is due to be installed in its new electric EX60 SUV that goes on sale next year.
And the system will continue to be tweaked and improved.
The safety belt will receive software upgraded via over-the-air updates sent to the car's electronic brain, meaning it will carry on developing.
Volvo boffins say that as its database of crashes increases, the 'car can improve its understanding of the occupants, new scenarios and response strategies'.
Åsa Haglund, who runs Volvo Cars' Safety Centre, added: 'The world first multi-adaptive safety belt is another milestone for automotive safety and a great example of how we leverage real-time data with the ambition to help save millions of more lives.
'This marks a major upgrade to the modern three-point safety belt, a Volvo invention introduced in 1959, estimated to have saved over a million lives.'
Located in Torslanda, Gothenburg, the centre has a movable (108 metres) test track with an enormous shifting arm (pictured here) that is used to adjust the point of impact from 0 to 90 degrees. This allows technicians can perform a variety of crashes from different angles
Volvo is a pioneer when it comes to vehicle safety. Most recently, it became the first manufacturer to use in-car cameras to monitor and alert drivers to drowsiness, and in 2020 became the first auto maker to install speed limiters (up to 112mph) in every vehicle it sells
Opened in 2000 in Torslanda, Gothenburg, the crash test laboratory has a capacity to carry out more than 400 full-scale tests per year
The new seatbelt's unveiling coincides with the 25th anniversary of the Safety Centre, which Volvo uses to 'recreate almost any traffic accident and perform tests that exceed regulatory requirements for real-world safety'.
Opened in 2020, the crash test laboratory has a capacity to conduct more than 400 full-scale tests per year.
Located in Torslanda, Gothenburg, it has one fixed (154 metre) and one movable (108 metres) test track.
The latter has an enormous shifting arm to that adjust the point of impact from 0 to 90 degrees so that technicians can perform a variety of crashes, such as frontal impacts, rear end collisions, side impacts, and collisions between two moving cars at different angles and speeds.

The two automakers have entered an agreement that would see Renault take 73.57% in the venture that would focus on producing and distributing cars in Brazil under the Renault and Geely brands. It is also due to make and distribute light commercial vehicles under the Renault brand to "attract new customers", according to a filing by Geely Auto. The deal is subject to regulatory approvals, the company said. Geely and Renault first announced their partnership to produce and sell zero- and low-emission vehicles in Brazil in February. The Brazilian partnership builds on the two companies' thermal engine joint venture headquartered in London and their jointly owned manufacturing plant in South Korea.

Abandoned UK car graveyard where fleet of 90s icons left to rot – including classic Cadillac & discontinued favourite

Read on to discover more UK car graveyards TIME CAPSULE Abandoned UK car graveyard where fleet of 90s icons left to rot – including classic Cadillac & discontinued favourite Click to share on X/Twitter (Opens in new window) Click to share on Facebook (Opens in new window) A HAUNTING graveyard of rotting vintage vehicles has been captured in the British countryside. Images show rusting motors lined up, including a nostalgic 90s Cadillac, in various states of disrepair. Sign up for Scottish Sun newsletter Sign up 2 A haunting graveyard of 90s motors was captured by an explorer Credit: YouTube/Road To Rust 2 Volvos and even a Cadillac were sighted in the eerie scrapyard Credit: YouTube/Road To Rust The scrapyard, which inhabits a crumbling UK farm, also includes dusty Micras and Volvos. The latter takes up most of the space, where a lineup of once eye-catching 240s and 244s eerily sit. Some of them don badges and stickers from their last days on the road. One Volvo in particular is likely a more recent addition as it sports a fresh-looking exhaust warning sticker. But others have seen better days. Some have been stacked, used to prop up even more scrap, their roofs caved in under the weight of other forgotten vehicles. And viewers may have to squint to identify a left-hand-drive Cadillac buried beneath overgrown bramble. This isn't the first time that classic cars have been left to rot in a barn. Over 40 abandoned motors from manufacturers such as BMW, Ford, Rover and Volvo were found in an open barn in the UK. A fleet of dilapidated fire engines covered in mould and peeling red paint were also found. Shocking moment speeding van driver distracted by phone slams into broken-down car leaving victim with lifelong injuries The images were taken by urban explorer Kyle Urbex during his 220th exploration at Brian's Vintage Car Collection in Chester. Kyle found the graveyard hidden away behind dense vegetation near the home of elderly couple Brian and Barbara. Other images show old tractors and JCBs scattered across the property, giving it an eerie abandoned atmosphere. He also found a BMW 635 CSI, once a sign of luxury, slowly being reclaimed by nature. With iconic styling and nicknamed 'shark nose' the motor was very much the symbol of the BMW range after being introduced in 1978. Kyle's visit took an unexpected turn when he stumbled upon Brian himself who revealed his hopes for the future. He said: "Brian has full intentions of one day being able to restore this high car collection, but given his age of 70+, I highly doubt he will get around to restoring all the cars and fire trucks. "He has been victim to some of the cars being smashed to bits by youths."

Simple mistake parents make during a heatwave could be deadly for your child

We've all got our children's best interests at heart but efforts to protect them could be putting them in danger Scotland is edging ever closer to the possibility of a heatwave, as a blast of hot weather and sunshine arrives in the UK this weekend. The Met Office has even gone as far as to issue a yellow health warning for much of England. For Scots, if Thursday and Sunday in particular play ball with high temperatures, we could establish an official heatwave of our own, too. This is when Scotland enjoys consistent mercury on or over 25C for three days in a row. ‌ However, while parents and children are frolicking in the sea, building sand castles in the beach, or playing in the garden, there is one simple mistake they could make in the heatwave that could be deadly for their children. ‌ A recent piece from Netmums has warned against the common practice of covering your baby's pram with a blanket or muslin on sunny days. Experts warn that this can lead to dangerously high temperatures inside the pram. You may do it to shield your wee ones from the sun or help them nap, but a covered pram can heat up like an oven in minutes, putting your baby at serious risk of overheating or even heatstroke. The Lullaby Trust charity warns that doing so could raise the risk of Sudden Infant Death Syndrome (SIDS). To illustrate the danger, childcare provider Sophie Campbell conducted an experiment using a thermometer and a child's doll. In a Facebook post, she explained how the temperature inside a covered pram or pushchair can rise. She dressed the doll, named Dolly, with factor 50, 5* UVA sunscreen, a drink for hydration, and a sun hat. Despite these precautions, she decided to cover Dolly with a blanket for shade and placed a thermometer inside. ‌ The temperature in the buggy started at 35C, but after just 12 minutes, it rose to 45C, and after another 15 minutes, it crept up to an alarming 50C. The gravity of the situation was clear for all to see, and Sophie used the example to urge parents to think again when using blankets for shade, as the potential consequences for a real child are horrendous. ‌ What's more, a cover can also hamper with a parent's ability to see their child therefore making it difficult for them to check on their tot or monitor their temperature. So, what is the alternative? The organisation advises using a clip-on sunshade or parasol for a pram or buggy. ‌ Svante Norgren, a paediatrician at a children's hospital in Stocklholm, threw weight behind the advice, telling Swedish newspaper Svenska Dagbladet: "It gets extremely hot down in the pram, something like a thermos. "There is also bad circulation of the air and it is hard to see the baby with a cover over the pram." ‌ Sophie went on: "It doesn't matter what you put over the top, a muslin, blanket or towel, the results will all be similar, and the outcome could be horrendous. 'Still to this day, I see babies/children in pushchairs on very sunny and hot days with blankets draped over them to block the sun and heat out." She ended with a final plea to parents, adding: "Please do not do this." Join the Daily Record WhatsApp community!
