Energy absorbers and vehicle interior parts

Abstract

The invention provides an energy absorber and a vehicle built-in part, and in particular relates to the energy absorber which can keep the energy absorption characteristic of ensuring passenger safety during vehicle collision, has high bounce and can be subjected to high impact, and the vehicle built-in part with the energy absorber. The energy absorber is arranged on the vehicle built-in part and between the vehicle built-in part and a vehicle body panel, and is characterized by being provided with a box body and a columnar part (12), wherein the box body is provided with a base (5) in a regular shape and side walls (6) which are continuously arranged along the periphery of the base (5); one surface (9) of the box body is provided with an opening; and the columnar part (12) is arranged in the box body and extends to the opening from the base (5). The vehicle built-in part is characterized by being provided with the energy absorber.

Description

technical field [0001] The present invention relates to an energy absorber that absorbs impact energy to protect an occupant during a side collision of a vehicle, and a vehicle interior component to which the energy absorber is attached. Background technique [0002] A variety of safety devices are installed inside the passenger compartment of the vehicle to protect the occupants from the impact of a collision. Interior parts are installed inside the passenger compartment to ensure comfort as a dwelling room, and safety devices are generally placed between the interior parts and the vehicle body panel. [0003] Patent Document 1 discloses a vehicle interior component that absorbs energy and deforms when it receives an impact from the side of the vehicle, so as to alleviate the impact received by the occupant and ensure safety. The interior member is arranged between a vehicle door trim and a vehicle body panel, and is a shock absorber that absorbs energy applied to the occu...

AI Technical Summary

Problems solved by technology

[0008] However, conventional energy absorbers (impact absorbers) are simply boxes, so there is a problem that the amount of absorbed energy has a limit

In other words, in order to absorb large energy, it is necessary to have a high reaction force, but if such a design is carried out, the size of the box will become large, and it will not be able to be accommodated between the vehicle interior parts and the body panel

In addition, if there is a reaction force by increasing the strength of the material, it may not be possible to alleviate the impact, resulting in a large impact energy being transmitted to the occupant.
