１６によつて座席が固定される。This embodiment relates to an expandable energy absorption mechanism. That is, reference numeral 13 designates a lower rail of the seat adjuster 10, which is fixed to a floor surface or the like by bolts 17. Reference numeral 12 designates an upper rail that is slidably attached to the lower rail 13, and the seat is fixed with seat attachment bolts 16.

Positioning collars 1 are placed on this rod 19 at an appropriate pitch.
A large number of protrusions 9a are formed. Furthermore, wedge-shaped dies 18 are attached to both ends of the rod 19 and fit inside the lower rail 13. Normally, this rod 19 is restrained from moving in the axial direction by the dies 18 at both ends, and the lock pawl 14 attached to the upper rail 12 is used to prevent the rod 19 from moving in the axial direction after adjusting the seat's longitudinal position. is engaged with an arbitrary collar 19a. Reference numeral 15 indicates a lever for engaging and disengaging the lock claw 14.

実に吸収される。At this time, the die 18 at one end of the rod 19 slides to spread out both side walls of the lower rail 13, as shown in FIG. The applied kinetic energy is absorbed by the force of the die 18, mostly by the plastic deformation force that expands both side walls of the array 13 and by the resistance of sliding friction. The device of the present invention, which has an energy absorption mechanism using the plastic deformation device of the embodiment described above, decelerates the occupant who is restrained in the seat with a seat belt by the energy absorption mechanism together with the seat in the first half of a vehicle collision. While moving forward and backward, most of the kinetic energy of the occupant and the seat is reliably absorbed through plastic deformation.

有している。The energy absorption mechanism using the plastic deformation device of the present invention is configured such that both side walls of the lower rail of the seat adjuster are expanded plastically deformed by a die fixed to the end of a rod integrated with the upper rail, so that the lower rail of the seat adjuster is plastically deformed. Compared to the conventional method where a dedicated plastic deformation member is made and attached to the bottom of the seat, it requires less space under the seat to place the plastic deformation member and a dedicated plastic deformation member. It is completely unnecessary, the conventional seat adjuster can be used as is, the structure is simple, and the cost is reduced, which is a significant effect.
