Abstract
A seat cushion includes a seat base frame, a cushion pad disposed on the seat base frame, and a skin material that covers the seat base frame and the cushion pad. The seat base frame includes a pair of side frames that extends in the front to back direction, a front elastic member that is installed in the pair of side frames and is in contact with the cushion pad, and a rear elastic member that is disposed while being separated from the front elastic member by a predetermined distance and is in contact with the cushion pad, in which a pad contact surface of the front elastic member is disposed to be inclined rearward with respect to a horizontal plane and a pad contact surface of the rear elastic member is disposed to be inclined forward with respect to the horizontal plane or to be parallel thereto.
Claims15
A seat cushion comprising:
- a seat base frame;
- a cushion pad which is placed on the seat base frame;
- and
- a skin material which covers the seat base frame and the cushion pad, wherein:
- the seat base frame comprises:
- a pair of side frames that extends in a front to back direction;
- a front elastic member that is installed in the pair of side frames and is in contact with the cushion pad;
- a rear elastic member that is separated from the front elastic member by a predetermined distance and is in contact with the cushion pad;
- and
- a plate-shaped frame installed in the pair of side frames,
- a pad contact surface of the front elastic member that is inclined rearward with respect to a horizontal plane;
- a pad contact surface of the rear elastic member that is inclined forward with respect to the horizontal plane or parallel thereto;
- a rear end of the plate-shaped frame is disposed in front of the front elastic member in a seat front-to-rear direction;
- the front elastic member and the rear elastic member are disposed while being separated from each other by a predetermined distance such that an ischial tuberosity of an occupant is positioned at a space between the front elastic member and the rear elastic member;
- and
- a front end of the front elastic member is located above a level of the rear end of the plate-shaped frame in a seat top-to-bottom direction.
A seat cushion comprising:
- a seat base frame;
- a cushion pad which is placed on the seat base frame;
