Problems solved by technology

If anyone sits on the seat bottom in the usable position and the leg parts are not positioned in the supporting position, the seat bottom may be deformed due to large loads
Thus, in use, conventional seats are fragile and prone to failure

Embodiment Construction

[0011] An embodiment of the present invention will be described with reference to the drawings. A tip-up vehicle seat 10 according to the invention comprises a seat back 11 attached to a vehicle body 13 via struts 12 and a retractable seat bottom 14 which is rotatable via support means 15 attached to the seat back 12. The seat bottom 14 is movable between a retracted position, in which the seat bottom becomes substantially parallel to the seat back 11, and an usable or horizontal position, in which the seat bottom It becomes substantially at right angles to the seat back 11 .

[0012] On the lower surface of the seat bottom 14 , a retractable leg member 17 is rotatably attached via a mounting shaft 16 . The leg member 17 is movable between a retracted position, in which the leg member becomes substantially parallel to the seat bottom 14, and a support position, in which the leg member becomes substantially parallel to the seat bottom 14. 14 are approximately at right angles...

Abstract

A tip-up vehicle seat comprises a seat back (11) attached to a vehicle body, a seat bottom (14) displaceable between a retracted position and a available position, a leg member (17) displaceable between a retracted position and a support position, a lock mechanism (18) arranged to hold the seat bottom at the retracted position. The lock mechanism (18) is connected to the leg member (17) through a wire cable (43) so that the lock mechanism (18) is unlocked by rotational movement of the leg member (17) from the retracted position toward the support position to release the restriction to the seat bottom (14).

Description

technical field [0001] The present invention relates to a tilt-up vehicle seat, and more particularly, to a tilt-up seat locking mechanism. Background technique [0002] Japanese Utility Model Application Laid-Open No. 4-14536 discloses a flip-up vehicle seat comprising: a seat back attached to the vehicle body, a seat bottom rotatably attached to the seat back , and a leg member rotatably attached to the seat bottom. The seat bottom is movable between a retracted position in which the seat bottom becomes substantially parallel to the seat back and an usable or horizontal position in which the seat bottom becomes Roughly at right angles to the seat back. The leg member is movable between a retracted position, in which the leg member becomes substantially parallel to the seat bottom, and a support position, in which the leg member becomes substantially parallel to the seat bottom. right angle. The seat bottom is held in the retracted position with a locking mechanism. ...
