Problems solved by technology

[0007] Although the collision energy absorbing structure like Patent Document 1 or Patent Document 2 can absorb the energy of the collision when a collision accident occurs, the function of slowly absorbing the collision energy during the collision is insufficient and the initial impact is relatively large. Therefore, it is necessary to Gradually lessen the shock transmitted to the passengers

Embodiment Construction

[0026] Below, according to figure 1 and Figure 2A , Figure 2B The shock absorbing member 1 for an automobile as the shock absorbing member according to the embodiment of the present invention will be described.

[0027] figure 1 The shock absorbing member (molded product of resin sheet) 1 for an automobile according to this embodiment shown is attached to the inside of a door of an automobile, between a body panel of a ceiling and an interior member, under a carpet, or inside a window frame on the side of the vehicle body. It is used to absorb the impact energy generated by collision accidents, etc., to ensure the safety of passengers. The shock absorbing member 1 for an automobile generally includes a base body 2 fixed to a vehicle body, a protrusion 3 protruding from the base body 2 , a rib 4 provided on the outer peripheral surface of the protrusion 3 , and a tipping prevention member 5 for preventing the protrusion 3 from falling.

[0028] The base body 2 is a member...

Abstract

Disclosed is an impact absorber with which the energy absorption characteristics during a collision can be set to specific characteristics. An impact absorber (1) for a motor vehicle is provided between a body panel and an interior member of the motor vehicle, and absorbs impact energy from a collision. The impact absorber comprises a base (2) which is fixed between the body panel and the interior member, and a plurality of protrusions (3) which protrude from the base and have the shape of a hollow cone or a truncated cone. The heights of the plurality of protrusions are not the same, and there are protrusions present which have differing numbers of ribs (4) constituting linear projections which project from the outer peripheral surface of said protrusions and are oriented from the tip ends of the protrusions towards the bases thereof. The ribs do not link adjacent protrusions, and are not disposed on a line joining the centres of adjacent protrusions.

Description

technical field [0001] The present invention relates to a shock absorbing member that is attached to a body panel of an automobile and an interior member such as a door and a ceiling to absorb shocks caused by a collision accident or the like. Background technique [0002] In recent years, shock absorbing members have been installed on the inner side of body panels and interior parts of automobiles to absorb shock energy generated by automobile collision accidents and the like to ensure the safety of passengers. [0003] According to Patent Document 1, there is proposed an energy absorbing structure including a base plate and a plurality of hollow cylindrical tubes integrally formed with the base plate and protruding vertically from the base plate. The energy absorbing structure absorbs energy by elastic deformation or plastic deformation of the pipe fittings, or elastic deformation and plastic deformation when subjected to a load, so as to reduce the impact on passengers. ...
