摘要:
The present invention relates to a steering column (1) for a motor vehicle, comprising a supporting unit (3) which can be connected to the body of the vehicle, and a casing unit (21), in which a steering spindle (22) is mounted such that it can be rotated about its longitudinal axis (23) and which is received in the supporting unit (3) such that it can be displaced in the longitudinal direction (L) parallel to the longitudinal axis (23), wherein an energy absorption device (5, 7, 73) is attached between the supporting unit (3) and the casing unit (21), which energy absorption device (5, 7, 73) comprises at least one first bending element (51, 71, 721) with an elongate entry limb (511) arranged parallel to the longitudinal direction, the free end (512) of said limb being connected to a first one of the two elements, the supporting unit (3) or to the casing unit (21), and the other end of said limb transitioning into a bend (513) which is adjoined by a fixed limb (514) connected to the other one of the two elements, the supporting unit (3) or to the casing unit (21). In order to make simplified production and reliable function possible in the event of a crash, the invention proposes that a second bending element (52, 72, 722) is of mirror-symmetrical configuration with respect to a first bending element (51, 71, 721) and is arranged in a mirror-symmetrically adjacent manner with respect to the first bending element (51, 71, 721).

An energy absorber comprising a housing for attachment to a first body, a deformer member mounted to the housing, a strip of plastically deformable material extending in a longitudinal direction between first and second ends, an attachment member provided at, or towards, the second end of the strip for attachment to a second body, the strip being arranged with the deformer member such that when a predetermined force is applied to the attachment member, the strip is moved relative to the deformer member from a first position in which a first section of the strip extends from the first end of the strip to the deformer member, to a second position in which at least a part of the first section of the strip is plastically deformed by the deformer member, wherein the strip is arranged such that when it is in its first position, the first section of the strip is substantially flat in the longitudinal direction of the first section of the strip.

A crash attenuator (100) for decelerating an impacting vehicle includes a first end (180) that can be releasably secured to a vehicle, and a second end (120) that is longitudinally spaced from the first end (180). The second end (120) includes an impact member (300) that is movable in the longitudinal direction from a pre-impact position to an impact position. At least a pair of deformable attenuator members (190) are spaced laterally and extend longitudinally between the first and second ends (180, 120). At least a portion of the attenuators (190) are bent in a non-outboard direction when the impact member (300) moves from the pre-impact position to the impact position.

Un élément de liaison (1) permet d'assembler deux éléments par une liaison de type encastrement. L'élément de liaison comprend une bande de tôle (2) comportant une première (3) et une seconde extrémité (4) aptes à être assemblées respectivement sur le premier et sur le second élément. La bande (2) comprend une portion d'enroulement (16) reliant les deux extrémités (3, 4), qui est roulée sur elle-même de manière à former un rouleau (30) hors duquel les deux extrémités (3, 4) émergent suivant le même sens de rotation, et qui est dimensionnée pour assurer la résistance en traction, torsion, et flexion entre les deux extrémités (3, 4) d'assemblage.

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. 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 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.
