Abstract
The present invention relates to a vehicle door impact absorption apparatus by which side impacts can be restricted during side impact intrusions to thereby provide increased protection for the vehicle occupants, the apparatus comprising two hollow supporting bars for inherently being disposed with a coil spring at an interior of a center pillar and for being resiliently inserted to thereby be fixed by a stopper protruded outside of a center pillar outer panel in order to reinforce a bracket facing a center pillar out of brackets which couple both tip ends of a door impact beam lengthwise disposed within front/rear doors to left/right tip end portions of an inner panel.
Claims23
A vehicle door impact absorption apparatus, comprising two hollow supporting bars with a coil spring at an interior of a center pillar, said coil spring being resiliently inserted in said supporting bars and fixed by a stopper protruding outside of an outer panel of the center pillar in order to reinforce one of two brackets facing the center pillar, each of the brackets being disposed in one of a front and rear door, and coupling a door impact beam lengthwise to an inner panel of its respective door.
A vehicle door impact absorption apparatus for a vehicle having front and rear doors separated by a center pillar, comprising:
- a door impact beam disposed in each of the front and rear doors;
- first and second supporting bars disposed in the center pillar;
- a coil spring for biasing the first and second supporting bars apart;
- and
- a stopper for releasably holding the first and second supporting bars together, said supporting bars being released upon impact to the stopper to allow each of the supporting bars to extend into a different one of the doors due to the biasing of the coil spring thereby reinforcing the door impact beams.
A center pillar for a vehicle, comprising:
- first and second supporting bars;
- a coil spring for biasing the first and second supporting bars apart;
- and
- a stopper for releasably holding the first and second supporting bars together, said supporting bars being released upon impact to the stopper to allow each of the supporting bars to move apart due to the biasing of the coil spring.
