Seat for car
First Claim
1. A car seat comprising:
- a catch part arranged inside a front portion of a seat cushion so as to be vertically movable, said portion lying in front of a rear end of a seated passenger said catch part extending in a width direction of said seat cushion;
means for urging said catch part to move upward; and
lock means operating with an inertial force upon an abrupt deceleration to inhibit vertical movement of said catch part.

Abstract
A catch member (14) extending in the width direction of a seat cushion (1) is arranged inside a front portion of the seat cushion (1) and is supported so as to be vertically movable. There are also provided a torsion spring (16) for urging the catch member (14) to move upward and a pendulum member (18) for operating with an inertial force upon an abrupt deceleration to inhibit vertical movement of the catch part. When a passenger sits on the seat cushion (1), the catch member (14) moves downward to preclude deterioration in seating comfort. When the passenger'"'"'s rear end (22) starts to move forward upon an abrupt deceleration, the catch member (14) is locked and the rear end (22) is caught by the catch member (14). This makes it possible to suppressed the forward movement of the passenger with reliability, and allow lightweight and low-cost configuration with simple configuration.

14. A car seat comprising a catch member arranged in a seat cushion so as to prevent a rear end of a passenger from slipping forward upon an abrupt deceleration, said catch member extending in a width direction of said seat cushion, wherein said catch member has at least two bend inducing portions except at its center in the width direction.

15. A car seat comprising a catch member arranged in a seat cushion so as to prevent a rear end of a passenger from slipping forward upon an abrupt deceleration, said catch member extending in a width direction of said seat cushion and being lifted up in front upon an abrupt deceleration, said catch member having a section modulus, said section modulus being larger in a direction of an input load than in a direction orthogonal thereto, said section modulus increasing the rigidity of said catch member.
