Abstract
A shock absorbing wall construction makes it possible to prevent the car from rolling over and protect the car occupant's head and neck in case of car crashes. The shock absorbing wall construction has a main shock absorber part or portion having an elastic and solid body and sub-shock absorber part or portion which is mounted on the upper front surface of the main shock absorber part. The lower front surface of the main shock absorber part curves concavely upward and forwardly outward from a lower end to its center to prevent the car from rolling over. The sub-shock absorber part projects forwardly along the length of the lower front surface and includes one or more air rooms or chambers inside it and piercing air vent holes which extend through the air chamber sidewalls so as to protect the passenger's head and neck.
Claims27
A shock absorbing wall comprising:
- a main shock absorber member formed of an elastic material, said main shock absorber member having a supporting portion at an upper portion thereof and a bottom forward edge;
- a sub-shock absorber member mounted on said supporting portion of said main shock absorber member;
- said main shock absorber member having a front surface, the front surface having a center area, a lower front surface, and a most forward portion at said center area, said lower front surface concavely extending from said bottom forward edge of said main shock absorber member to said center area of said front surface;
- and
- the sub-shock absorber member projecting forward of the bottom forward edge of the main shock absorber member at least as far as said most forward portion of said front surface of the main shock absorber member and having an air chamber with air vent holes communicating with the air chamber to vent air out of said main shock absorber member, said vent holes being dimensioned so as to permit air to escape gradually during a crash impact.

A shock absorbing wall comprising:
- a main shock absorber member formed of an elastic material, said main shock absorbing member having a supporting portion at an upper portion thereof and a bottom forward edge;
- a sub-shock absorber member mounted on said supporting portion of said main shock absorber member;
- said main shock absorber member having a front surface with a center area, a lower front surface concavely extending from said bottom forward edge of said main shock absorber member to said center area of said front surface, and a most forward portion at said center area;
- the sub-shock absorber member projecting forward of the bottom forward edge of the lower front surface at least as far as said most forward portion of said front surface of the main shock absorber member and having an air chamber with air vent holes communicating with the air chamber to vent air out of said main shock absorber member, said vent holes being dimensioned so as to permit air to escape gradually during compression of said air chamber;
- and
- at least one of said air vent holes having a bushing disposed therein to maintain an open channel during compression of said air chamber.
