20120228889 | VEHICLE BUMPER DEVICE - A bumper reinforcement is provided with a front wall portion, an upper wall portion, and a lower wall portion. The front wall portion constitutes the front portion of the bumper reinforcement. The upper wall portion is connected to the upper edge of the front wall portion and constitutes the upper half of the rear portion of the bumper reinforcement. The lower wall portion is connected to the lower edge of the front wall portion and constitutes the lower half of the rear portion of the bumper reinforcement. Outer grooves are formed by denting the front wall portion rearward and extend along the vehicle width direction. The upper wall portion comprises a top wall which constitutes the top of the upper wall portion. Upper grooves are formed by denting the top wall downward, and are located intermittently along the aforementioned width direction. Furthermore, the upper grooves extend in the longitudinal direction. The lower wall portion comprises a bottom wall which constitutes the bottom of the lower wall portion. Lower grooves are formed by denting the lower wall portion upward, and are located intermittently along the aforementioned width direction. Furthermore, the lower grooves extend in the longitudinal direction. | 09-13-2012 |
20130001963 | SHOCK ABSORBER AND BUMPER DEVICE FOR VEHICLE - A shock absorber includes a cylindrical small diameter portion, a cylindrical large diameter portion, and an annular step portion that connects the small diameter portion and the large diameter portion to each other. The shock absorber absorbs load applied thereto through plastic deformation that starts at the annular step portion thereby absorbing impact energy. In the deformation, the small diameter portion is folded back into the large diameter portion. The large diameter portion has protrusions, which extend in the axial direction and protrude radially outward. Therefore, the shock absorber stabilizes turning deformation and is capable of efficiently absorbing impact energy. A bumper device for a vehicle is also provided. | 01-03-2013 |
20130076052 | CRUSH BOX AND VEHICLE BUMPER APPARATUS INCLUDING THE SAME - A crush box arranged between a side member of a vehicle body and a bumper reinforcement member, the crush box including: a main body portion arranged in a longitudinal direction of a vehicle and formed in a tubular shape, the main body portion having first and second portions; a vehicle body attaching portion arranged at a first end of the main body portion; and a bumper attaching portion arranged at a second end of the main body portion, wherein vertical cross-sections of both the first portion adjacent to the vehicle body attaching portion and the second portion adjacent to the bumper attaching portion are polygonal shapes, and the number of vertices of the polygonal shape of the vertical cross-section of the second portion is greater than the number of vertices of the polygonal shape of the vertical cross-section of the first portion. | 03-28-2013 |
20130099514 | VEHICLE BUMPER APPARATUS AND CRUSH BOX THEREOF - A vehicle bumper apparatus includes a bumper reinforcement member formed to have a hollow cross section and including a vehicle interior portion formed to have an open cross section including an opening, and a crush box supporting the bumper reinforcement member to mount the bumper reinforcement member to a side member of a vehicle body, the crush box including a connecting portion arranged at a vehicle exterior portion, the connecting portion closing the opening of the bumper reinforcement member to restrict the opening from being expanded, and a retaining portion protruding from the connecting portion toward an exterior side of a vehicle to retain the bumper reinforcement member. | 04-25-2013 |
20130113224 | BUMPER REINFORCEMENT - A bumper reinforcement includes end portions and an intermediate portion, wherein the bumper reinforcement is made of a light alloy extruded material including a hollow cross-section and is configured to be arranged at a vehicle, the bumper reinforcement is configured to be assembled on and supported by a supporting member at each of the end portions bent toward a vehicle body side, the hollow cross-section includes a closed cross-section at the intermediate portion and includes an open cross-section provided with an opening at each of the end portions, each of the end portions is formed in a manner that a thickness of the hollow cross-section thereof in a vehicle front-rear direction is gradually reduced toward an end, and each of the openings is configured to be at least partially closed with a connecting portion of the supporting member and is restricted from being expanded. | 05-09-2013 |
20130241218 | VEHICLE BUMPER REINFORCEMENT - Provided is a vehicle bumper reinforcement including: an inner-wall section in a long shape along the width direction of a vehicle; an outer-wall section formed in a long shape so as to be arranged to face the inner-wall section; an upper-wall section connecting an upper end side of the inner-wall section and an upper end side of the outer-wall section; and a lower-wall section connecting a lower end side of the inner-wall section and a lower end side of the outer-wall section. The inner-wall section has a first concave section with a bottom, which is formed along a longitudinal direction thereof, the outer-wall section has a second concave section with a bottom, which is formed along a longitudinal direction thereof, and a bottom surface of the first concave section and a bottom surface of the second concave section are arranged to face each other. | 09-19-2013 |
20130241219 | CRASH BOX AND BUMPER DEVICE - Provided is a crash box to be installed to a bumper reinforcement including an outer-wall section, an upper-wall section and a lower-wall section, an upper inner-wall section, a lower inner-wall section, and a clearance between the upper inner-wall section and the lower inner-wall section. The crash box includes a body section provided between a member of a vehicle body side and the bumper reinforcement, an upper support section provided to protrude from the body section to a bumper reinforcement side, a lower support section provided to protrude from the body section to the bumper reinforcement side, and an insertion section provided to protrude from the body section to the bumper reinforcement side, inserted from the clearance into the bumper reinforcement and contacting a lower end portion of the upper inner-wall section and an upper end portion of the lower inner-wall section. | 09-19-2013 |
