VEHICLE SEAT

摘要

A seat pad includes a main portion and a bank portion. When the seat pad is disposed on a seat frame, a reverse face side of the bank portion contacts the seat frame to be supported. When the bank portion is pressed in a seat width direction, the bank portion is flexurally deformed so as to be crushed around a contact portion contacting the seat frame. A contact member is relatively movably provided on a side of the backing material that faces the seat frame, and the seat pad is disposed on the seat frame while the contact member is pressed against the seat frame. When the bank portion is pressed in the seat width direction, the backing material and the seat pad including the bank portion move in a crushing direction relatively to a portion of the contact member that contacts the seat frame.

1. A vehicle seat comprising:
a seat frame that constitutes a frame of the vehicle seat; a seat pad that forms an outer shape of the vehicle seat and that elastically supports an occupant; a planar backing material that is integrated with the seat pad and that covers a reverse face of the seat pad; and a planar contact member that is harder than the backing material, wherein: the seat pad includes a main portion that allows the occupant to be seated, and a bank portion that is disposed at an outer side of the vehicle seat with respect to the main portion, and that protrudes toward a seating side; when the seat pad is disposed on the seat frame, the main portion is disposed in the seat frame, and a reverse face side of the bank portion contacts the seat frame so as to be supported by the seat frame; when the bank portion is pressed in a width direction of the vehicle seat, an end portion side of the seat pad that constitutes the bank portion is flexurally deformed so as to be crushed around a contact portion that contacts the seat frame; the contact member is provided on a side of the backing material that faces the seat frame such that the contact member is movable relatively to the backing material, and the seat pad is disposed on the seat frame while the contact member is pressed against the seat frame; and when the bank portion is pressed in the width direction of the vehicle seat, the backing material and the seat pad including the bank portion move in a crushing direction relatively to a portion of the contact member that contacts the seat frame.
