Abstract: A retractable vehicle seat in which a seat main body disposed on a vehicle floor is flipped up laterally, so as to be retracted in a vehicle interior side wall of which the upper portion is inwardly inclined, may include a connection mechanism that is configured to rotatably connect the seat main body to a support stand. The connection mechanism includes a four-link mechanism having a stationary link integral with the support stand, an intermediate link integral with the seat main body, and a first link and a second link that connect these two links. The second link is configured to increase an angle between the first link and the intermediate link as the seat main body is flipped up.

Abstract: A lock device that includes a lock mechanism provided on one of two members to be engaged with each other, and a striker provided on the other of the two members. The lock mechanism may include a first contact point in which a pawl contacts a hook in the unlocked condition by an elastic force of a lock spring and a second contact point in which a cam contacts the hook in the unlocked condition by an elastic force of a push spring. The hook, the pawl and the cam are arranged and constructed such that these contact points are separately set at different positions. Further, the second contact point is in a certain position.

Abstract: A spring force of a thrust spring can be determined independently of a spring force of a locking spring, reducing an operating load of an unlocking operation. A locking device includes a locking mechanism provided on one of two members to be engaged with each other, and a striker provided on the other of the two members. The locking mechanism includes a base plate, a hook, a pawl, a cam, a locking spring, a thrust spring and a canceling plate. The base plate has a recess that is capable of receiving the striker. The hook, when rotated relative to the base plate, is capable of forming a locked condition in which the striker is held between the hook and the recess of the base plate or an unlocked condition in which the hook is spaced away from the striker. The pawl is capable of rotating relative to the base plate and maintaining the hook in the locked condition. The cam is capable of further pressing the hook in the locked condition toward a locking direction.

Abstract: A locking device includes a locking mechanism and a striker. A hook of the locking mechanism, when rotated, is capable of forming a locked condition in which the striker is held between the hook and a recess of a base plate. A pawl is capable of rotating to a position in which the pawl can engage the hook and maintaining the hook in the locked condition. A locking spring is capable of biasing the hook and the pawl such that the hook and the pawl are stabilized in the locked condition or the unlocked condition. A thrust member is capable of rotating to a thrusting position in which the thrust member can press the hook in the locked condition toward a locking direction via a cam surface formed therein. A thrust spring is capable of biasing the thrust member toward the thrusting position. A through hole that is formed in the thrust member forms a deformation promoting portion.
