  • Patent number: 10099590
    Abstract: A headrest support structure includes: a support member configured to support a protruding member projecting from a headrest; a bracket provided in a seatback and having an accommodation chamber in which the support member is accommodated in a tiltable manner in a front-rear direction perpendicular to a width direction of the headrest; a spring provided in the accommodation chamber and deforming in a bending manner due to tilting of the support member relative to the bracket in the front-rear direction; and a projection portion projecting, in the front-rear direction, from one of an outer surface of the support member and an inner surface of the bracket which are opposed to each other. The projection portion is provided at a position different from the spring in a regulation direction perpendicular to both the front-rear direction and the width direction of the headrest.

  • Patent number: 9884573
    Abstract: A headrest supporting structure is provided with a lower spring and an upper spring, which are located at different positions in the vertical direction of a seat. The structure elastically supports a headrest stay with the springs. When a stopper section, which changes the position in the front-back direction in accordance with pivoting of the headrest, comes into contact with a support bracket, further pivoting of the headrest is restricted. The stiffness of the upper spring located relatively distant from the stopper section in the seat vertical direction is higher than that of the lower spring located closer to the stopper section.
