The problem appears at the exact moment it stops without warning.<\/p>\n<h2>What actually happens in a crash<\/h2>\n<p>When a car hits an obstacle, it stops over the length it is able to deform: about half a metre for a modern car at 50 km\/h. The occupants, held by belts and airbags, stop with it.<\/p>\n<p>Whatever is not attached carries on at 50 km\/h. It will only stop when it meets something: a seat back, a headrest, someone's neck.<\/p>\n<p>The arithmetic is not mysterious. Going from 13.9 metres per second to zero over half a metre is a deceleration of roughly twenty times gravity. An object therefore takes a force equal to twenty times its weight.<\/p>\n<ul>\n<li>A 1.5-litre bottle of water hits like <strong>30 kg<\/strong>.<\/li>\n<li>A 2 kg laptop hits like <strong>40 kg<\/strong>.<\/li>\n<li>A 5 kg bag of shopping hits like <strong>100 kg<\/strong>.<\/li>\n<li>A 10 kg toolbox hits like <strong>200 kg<\/strong>.<\/li>\n<\/ul>\n<p>These are not brochure figures: it is elementary arithmetic, and it is why safety testing has long called for restraint nets behind the seats of estate cars.<\/p>\n<h2>The three places that cause trouble<\/h2>\n<p><strong>The parcel shelf.<\/strong> The worst place in the cabin: nothing holds the object, it sits at head height, and it crosses the whole interior in a straight line. People still put tissue boxes, umbrellas and speakers there.<\/p>\n<p><strong>The passenger seat.<\/strong> An unused belt holds nothing at all, and a bag put there heads for the windscreen or the footwell &mdash; where your pedals are, including during a merely firm braking.<\/p>\n<p><strong>The boot of an estate or an SUV with no cover.<\/strong> With no net and no bulkhead, the boot is open to the cabin. A suitcase there has the whole length of the car to accelerate before meeting a seat back.<\/p>\n<h2>What works, in order<\/h2>\n<p>The general rule fits in one sentence: the heavier it is, the lower, further back and more wedged in it must be.<\/p>\n<ol>\n<li><strong>The boot floor, against the rear seat backs.<\/strong> The safest position for anything heavy. An object pressed against the seat back cannot build up speed.<\/li>\n<li><strong>A net or a bulkhead<\/strong> if you regularly carry volume, or if you drive with a dog.<\/li>\n<li><strong>Hanging vertically<\/strong> for the soft bags of daily life. A <a href=\"\/en\/product\/crochet-appui-tete-voiture-rangement\/\">headrest hook<\/a> holds the bag against the seat back instead of leaving it loose on a seat. The load stays low, pressed flat, and out of the footwell.<\/li>\n<li><strong>Nothing on the parcel shelf<\/strong>, ever. It is the cheapest habit to adopt and the one that changes the most.<\/li>\n<\/ol>\n<p>A hook is obviously not an approved safety device, and we do not sell it as one: it keeps a bag from lying around and sliding under the pedals. To carry something heavy and hard, the only right answer is still the boot floor.<\/p>\n<h2>Children and animals<\/h2>\n<p>In the back, the danger rarely comes from a forgotten object: it comes from what we hand children during the trip. A tablet held at arm's length, a metal flask, a rigid toy. Prefer soft and light, and keep the rest in a seat-back pocket rather than on the bench.<\/p>\n<p>For a dog, no amount of storage replaces a safety harness or a secured crate. An unrestrained twenty-kilo animal represents, in a 50 km\/h crash, the equivalent of four hundred kilos thrown forward.<\/p>\n<h2>What to take away<\/h2>\n<p>There is no harmless object in a car, only objects that are well or badly placed. Walking round your cabin once, deciding on a place for each thing, and sticking to it: that is five minutes, once.<\/p>","protected":false},"excerpt":{"rendered":"<p>Ce que devient une bouteille de 1,5 L dans un choc \u00e0 50 km\/h, les trois endroits \u00e0 \u00e9viter, et ce qui fonctionne vraiment.<\/p>","protected":false},"author":0,"featured_media":0,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[1],"tags":[],"class_list":["post-152","post","type-post","status-publish","format-standard","hentry","category-conseils"],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v28.2 -
