A stowable vehicle seat having improved operability and safety at the time of seat stowage are provided. A seat having a seat cushion back includes a foot lock mechanism for inhibiting the rotating of the cushion, a reclining lock mechanism for inhibiting the rotating of the seat back, a strap pullable toward any pull direction, and a lock releasing mechanism for keeping/releasing the rotate inhibiting states of the foot lock mechanism and the reclining lock mechanism by the pulling operation of the strap. When the pull direction of the strap is a horizontal direction, the lock releasing mechanism releases the rotate inhibiting states of both the foot lock mechanism and the reclining lock mechanism, and when the pull direction of the strap is an upward direction, the lock releasing mechanism keeps the rotate inhibiting states of both the foot lock mechanism and the reclining lock mechanism.

1. A stowable vehicle seat, comprising: a seat cushion that is rotatable with respect to a vehicle body floor surface and a seat back, mounted to the seat cushion to be rotatable with respect to the seat cushion and is foldable by a rotating of the seat cushion and the seat back:the stowable vehicle
1. A stowable vehicle seat, comprising: a seat cushion that is rotatable with respect to a vehicle body floor surface and a seat back, mounted to the seat cushion to be rotatable with respect to the seat cushion and is foldable by a rotating of the seat cushion and the seat back:the stowable vehicle seat further comprising: a foot lock mechanism for inhibiting the rotating of the seat cushion;a reclining lock mechanism for inhibiting the rotating of the seat back;a strap pullable toward any pull direction; anda lock releasing mechanism for keeping and releasing the rotate inhibiting states of the foot lock mechanism and the reclining lock mechanism via the pulling operation of the strap,the lock releasing mechanism being configured so that: in a case where the pull direction of the strap is a first direction within a predetermined angular range, the rotate inhibiting states of both the foot lock mechanism and the reclining lock mechanism are released; andin a case where the pull direction of the strap is a second direction out of the predetermined angular range, the rotate inhibiting states of both the foot lock mechanism and the reclining lock mechanism are kept. 2. The stowable vehicle seat according to claim 1, wherein the lock releasing mechanism comprises: a foot lock releasing cable, which is pulled by the pulling operation of the strap to release the rotate inhibiting state of the seat cushion;a reclining lock releasing cable, which is pulled by the pulling operation of the strap to release the rotate inhibiting state of the seat back;a foot lock releasing link, which is disposed between the strap and the foot lock releasing cable and can be displaced between a connection position in which the foot lock releasing cable can be pulled by the pulling operation of a strap link and a disconnection position in which the connection is released and the foot lock releasing cable cannot be pulled;a reclining lock releasing link, which is disposed between the strap and the reclining lock releasing cable and can be displaced between a connection position in which the reclining lock releasing cable can be pulled by the pulling operation of the strap link and a disconnection position in which the connection is released and the reclining lock releasing cable cannot be pulled; anda select link, which is disposed in a position that is contactable with the strap and can be moved coupled with the strap by the contact with the strap, andthe select link is configured so that: in the case where the pull direction of the strap is the first direction, both the foot lock releasing link and the reclining lock releasing link are kept in the connection position; andin the case where the pull direction of the strap is the second direction, the select link comes into contact with the strap and moves coupled with the strap to displace both the foot lock releasing link and the reclining lock releasing link to the disconnection position. 3. The stowable vehicle seat according to claim 2, further comprising: a pivotal support that pivotally supports both the foot lock releasing link and the reclining lock releasing link to be rotatable with respect to the seat back;whereinthe select link rotates the foot lock releasing link and the reclining lock releasing link to the disconnection position in the case where the pull direction of the strap is the second direction. 4. The stowable vehicle seat according to claim 3, wherein: the foot lock releasing link and the reclining lock releasing link each have an elongated hole whose lengthwise direction coincides with the pull direction of the strap, are rotatably supported on a pivot inserted through the elongated hole, and can slide along the lengthwise direction. 5. The stowable vehicle seat according to claim 2, wherein: the select link has a strap insertion hole through which the strap is inserted; andin the case where the pull direction of the strap is the second direction, the strap comes into contact with an inner wall face defining the strap insertion hole, and the select link moves in the second direction coupled with the strap. 6. The stowable vehicle seat according to claim 2, wherein: the strap has a strap link, on which a pair of projecting strap pins are provided, on a proximal end part side; andthe foot lock releasing link and the reclining lock releasing link have engagement claws that are engagable with the paired strap pins, the strap pin and the engagement claw becomes in an engaged state in a connection position, and the engaged state of the strap pin and the engagement claw is released in a disconnection position. 7. The stowable vehicle seat according to claim 2, wherein: the lock releasing mechanism further comprises a sub link which is disposed in a position that is contactable with the select link and can come into contact with either one of the foot lock releasing link and the reclining lock releasing link;in a case where the pull direction of the strap is a third direction which is opposite to the second direction with the first direction being the reference, the select link moves toward the third direction coupled with the strap and comes into contact with the sub link; andthe sub link comes into contact with either one of the foot lock releasing link and the reclining lock releasing link due to the contact with the select link, and displaces it to the disconnection state. 8. The stowable vehicle seat according to claim 7, wherein: one end side of the sub link is pivotally supported on either one of the foot lock releasing link and the reclining lock releasing link, and an other end side thereof is provided with a projecting sub link pin that presses the side face of the other releasing link; andby the contact of the select link, the side face of the other releasing link is pressed and displaced to the disconnection state. 9. The stowable vehicle seat according to claim 7, wherein: the projecting select pin is provided with a select link pin;on one side of the select link near the select link pin along the pull direction of the strap, the foot lock releasing link and the reclining lock releasing link are arranged; andon the other side along the pull direction of the strap, the sub link is arranged. 10. The stowable vehicle seat according to claim 7, wherein: the select link has a strap insertion hole through which the strap is inserted;in the case where the pull direction of the strap is the second direction, the strap comes into contact with the inner wall face on the side along the pull direction of the strap insertion hole, and the select link moves in the second direction coupled with the strap; andin the case where the pull direction of the strap is the third direction, the strap comes into contact with an inner wall face on the opposite side to the inner wall surface of the strap insertion hole, and the select link moves in the third direction coupled with the strap.
