![]() ![]() With the aim of meeting various government test standards, particularly in Europe with the European Enhanced Vehicle-Safety Committee (EEVC) and in Japan, many improvements to bumpers are designed so that the bumper assembly provides a sufficient level of pedestrian injury mitigation and protects pedestrians' legs when struck by an automobile at a speed of 40 km/h.Īutomotive bumpers typically comprise several components, separately manufactured and then assembled, which include a stiff reinforcing beam, a soft energy absorber, a lower bumper stiffener and a fascia surrounding the energy absorber and having primarily aesthetic and aerodynamic functions. In addition, bumper systems are government-regulated and must meet legislated. BACKGROUND OF THE INVENTIONīumpers are used on vehicles to absorb shock and impact from collisions and to thereby prevent or minimize injury to passengers and to curtail damage to the vehicle. The present invention relates to the field of automotive bumper assemblies for pedestrian safety, particularly to the field of energy absorbers. A method of reducing collision energy transmitted to a pedestrian comprising the step of: attaching the energy absorber of claim 1 to a vehicle selected from the group consisting of a motorized vehicle, an automobile and a truck. A vehicle having the bumper assembly of claim 11, wherein the vehicle is selected from the group consisting of a motorized vehicle, an automobile and a truck.ġ3. A bumper assembly comprising the energy absorber of claim 1, a reinforcing beam and a fascia, the energy absorber being interposed between the reinforcing beam and the fascia.ġ2. The energy absorber of claim 9 made by extrusion.ġ1. The energy absorber of any preceding claim, made by injection molding, blow molding or extrusion.ġ0. ![]() The energy absorber of any preceding claim, wherein the thermoplastic material is polybutylene terephthalate (PBT).ĩ. The energy absorber of any preceding claim, wherein the thermoplastic material is made of a polyester or thermoplastic elastomers defined in ISO 18064:2003(E).Ĩ. The energy absorber of any preceding claim, wherein the thickness is variable and is between at or about 2 mm and at or about 6 mm.ħ. The energy absorber of any preceding claim, wherein the rear wall (b) has a thickness (t-b) between 0.03 w and 0.05 w.Ħ. The energy absorber of any preceding claim, further comprising a rear wall (b) that circumferentially closes the energy absorber.ĥ. The energy absorber of any preceding, further comprising a rear wall (b) that circumferentially closes the energy absorber.Ĥ. The energy absorber of claim 1, wherein the thickness of the top wall (t-c) and the thickness of the bottom wall (t-d) are equal.ģ. (measured according ISO 527-1/-2) b) yield strength between 30 and 40 MPa (measured according ISO 527-1/-2) c) modulus of elasticity between 1000-1500 MPa (measured according ISO 527-1/-2) and d) hardness Shore D between 50 ShD and 80 ShD (measured according ISO 868).Ģ. An energy absorber having a width w, a height h, a front wall a, a top wall c and a bottom wall d wherein: 1) the height h is between 0.8 w and 1.0 w 2) a thickness of the front wall (t-a) is between 0.06 w and 0.09 w 3) a thickness of the top wall (t-c) is between 0.03 w and 0.09 w 4) a thickness of the bottom wall (t-d) is between 0.03 w an 0.09 w and 5) the energy absorber is made substantially of a thermoplastic material having the following: a) elongation at break higher than 20% between −20° C. ![]() And the ability to browse while keeping an eye on your Facebook account means that you might actually get some work done.1. But no matter the one-click access to Facebook overshadows any negatives. There's a lot of wasted space that could be put to good use, even if it's not Facebook related. That's really our only complaint with this free toolbar: the lack of customization options. The search feature, like the rest of the toolbar, is only for Facebook, and you won't find any of the typical extras like weather information or e-mail notification. A button on the toolbar activates the sidebar so you can keep tabs on your Facebook friends, while the Share button lets you easily share a Web page with them while you're browsing. You'll also find links that take you to your profile, in-box, photos, and account settings. We did find that if you already have the Facebook site open, you'll need to refresh the page for any changes made from the toolbar to take effect. It allows you to log in to your account and even change your status. The aptly named Facebook Toolbar holds a host of buttons and links to keep you in touch with what's happening on the popular social networking site. ![]() It offers one-click access to your Facebook account while you browse the Web. If you're one of the thousands of Facebook users who find themselves constantly signing into and checking your account, this free Firefox add-on is sure to feed your addiction. ![]()
