Abstract
The present invention the related to a shock absorption pad for a vehicle for protecting occupant's lower legs. The shock absorption pad according to the present invention on which an occupant's foot is placed is attached on a surface of a toe board. The shock absorption pad includes a first shock absorption layer provided on the occupant's foot-placing side for absorbing an impact generated in a boundary region at which an energy absorption load of a vehicle body becomes different in a deformation process of the vehicle body at a vehicle crash, and a second shock absorption part provided on the toe board's side for absorbing an impact generated in a region in which the energy absorption load is high.
Claims8
A shock absorption pad for a vehicle which is attached on a surface of a toe board and on which an occupant's foot is placed, comprising:
- a first shock absorption part provided on the occupant's foot-placing side for absorbing an impact force generated in a boundary region at which an energy absorption load of a vehicle body becomes different in a deformation process of the vehicle body at a vehicle crash, the first shock absorption part being divided in a plane over the occupant's foot-placing area to lower an in-plane rigidity of the first shock absorption part during a compressive deformation;
- and
- a second shock absorption part provided facing the toe board for absorbing an impact generated in a region in which the energy absorption load is high,
- wherein an energy absorption load per unit area of the first shock absorption part is lower than an energy absorption load per unit area of the second shock absorption part.
A shock absorption pad for a vehicle which is attached on a surface of a toe board and on which an occupant's foot is placed, wherein
- the shock absorption pad is a foam-molded component made from a resin and is provided with a plurality of projections on the occupant's foot-placing side, said projections being spaced from each other in a plane over the occupant's foot-placing area to lower an in-plane rigidity of the shock absorption pad on the occupant's foot placing side during a compressive deformation.
A vehicle, comprising a toe board and a shock absorption pad, the shock absorption pad comprising:
- a first shock absorption part provided on an occupant's foot-placing side for absorbing an impact force generated in a boundary region at which an energy absorption load of a vehicle body becomes different in a deformation process of the vehicle body at a vehicle crash, the first shock absorption part being divided in a plane over the occupant's foot-placing area to lower an in-plane rigidity of the first shock absorption part during a compressive deformation;
- and
- a second shock absorption part provided facing the toe board for absorbing an impact generated in a region in which the energy absorption load is high,
- wherein an energy absorption load per unit area of the first shock absorption part is lower than an energy absorption load per unit area of the second shock absorption part.
