A strengthening structure of a vehicle is provided that comprises a base having a first plurality of cutouts and relief members disposed across the base. Each relief member includes a cross section having a plurality of corners forming a plurality of inner and outer angles, a distal end, and an open proximal end in communication with one of the first plurality of cutouts.

An impact absorber that is capable of inhibiting variation in performance by controlling buckling behavior. An impact absorber including a hollow blow molded article, wherein the blow molded article includes a front wall and a back wall separated into front and back and facing each other and a side wall connecting the front wall with the back wall, the front wall includes a tubular front side concave rib formed by indenting the front wall, the back wall includes a tubular back side concave rib formed by indenting the back wall, and the front side concave rib and the back side concave rib have distal end portions welded to each other, at least one of the front side concave rib and the back side concave rib has a buckling induction section formed as origin of buckling for impact absorption.

A shock absorbing structure of a vehicle door including a vehicle body panel with a service hole includes a door trim and a shock absorber. The door trim covers the vehicle body panel from an interior side of a vehicle. The shock absorber is mounted to the vehicle body panel to cover the service hole. The shock absorber includes a shock absorbing portion that is inserted in the service hole. The shock absorbing portion is disposed such that an end of the shock absorbing portion on an exterior side of the vehicle is disposed more to the exterior side of the vehicle than the service hole and between the vehicle body panel and the door trim.

A vehicle door includes a door inner and a trim panel fixed to the door inner. An energy absorber having a vehicle-rearward end and a vehicle-forward end is disposed between the door inner and the trim panel and elongated in a vehicle-forward direction from the vehicle-rearward end to the vehicle-forward end. The energy absorber includes a first energy-absorbing component defining a cavity facing the trim panel, and a second energy-absorbing component disposed in the cavity. The energy absorber has a stiffness that decreases in the vehicle-forward direction.

An integrated knee bolster device for a vehicle is configured to restrict the depth of penetration of the knees of a seat occupant which strike a lower crash pad panel when a vehicle collision occurs, thus minimizing injury to the seat occupant, and enhancing safety performance for the seat occupant.

A vehicle footrest impact deflection member includes a first portion and a second portion. The first portion is configured to be disposed outboard of a vehicle trim panel. The first portion includes a non-collapsible part having a first overall density. The second portion extends inboard from the first portion. The second portion includes a collapsible part having a second overall density that is less dense than the first overall density of the non-collapsible part.

To make it possible to make impact absorption at the time of a collision even when there is no sufficient space.

[Solution] An impact absorption member according to the present invention includes: a member that is placed adjacent to an exterior material 110 of an automobile and in which a height in a direction orthogonal to the exterior material is larger than a width in a direction along the exterior material in a cross section orthogonal to an extending direction of the member. By this configuration, a first member 122 and a second member 124 are arranged so as to extend in different directions and be adjacent to the exterior material 110 of an automobile, and therefore impact absorption at the time of a collision can be made even when there is no sufficient space.

A vehicle footrest impact deflection member includes a first portion and a second portion. The first portion is configured to be disposed outboard of a vehicle trim panel. The first portion includes a non-collapsible part having a first overall density. The second portion extends inboard from the first portion. The second portion includes a collapsible part having a second overall density that is less dense than the first overall density of the non-collapsible part.

A side pillar air curtain guide includes a main body having a ramp receiver and an air curtain ramp insert connected to the main body. The air curtain ramp receiver insert includes a plurality of ribs projecting from the main body at an acute included angle with the main body.

A shock absorber formed such that at least part of an end wall of a groove rib is a fragile portion, or a shock absorber that makes a fracture behavior according to a design intent. The shock absorber has a hollow molded-body having a hollow. The hollow molded-body includes front and rear walls that are spaced from and opposed to each other and a side wall that connects the front and rear walls. The side wall is provided with a front groove rib formed by recessing the front wall and a rear groove rib formed by recessing the rear wall. A side groove wall is formed by welding together at least parts of end walls of the front groove rib and the rear groove rib.
