  • Patent number: 11376994
    Abstract: Provided is a vehicle seat having a pitching function, which not only has an assist function for bringing a main frame to a seated position or a forward tilted position, but also prevents the increase in the width and the increase in the weight of the seat. The vehicle seat includes: a base frame; a main frame disposed on the base frame and having a back frame and a cushion frame; and a link mechanism that allows the main frame to swing to the seated position and the forward tilted position with respect to the base frame. A third rotating shaft of the link mechanism is provided with a torsion spring that urges the main frame to swing from the forward tilted position to the seated position.

  • Publication number: 20220194272
    Abstract: A vehicle seat that can suppress damage to an on-board object is provided. In each side frame of a cushion frame, an eccentric portion is eccentric outward in a right-left direction with respect to a base portion, and in each side frame of a back frame, an eccentric portion is eccentric inward in the right-left direction with respect to a base portion. Thus, when the load at the time of rear collision acts, each side frame of the cushion frame easily becomes deformed outward in the right-left direction, and each side frame of the back frame easily becomes deformed inward in the right-left direction. Accordingly, the deformation direction of each side frame of the cushion frame and the deformation direction of each side frame of the back frame can be easily made opposite to each other, and the deformations of the respective side frames and can be inhibited.
