Abstract

A detachable vehicle seat includes: a seat cushion including a seat latch for selectively securing the seat cushion to a vehicle body, and a seat control device for selectively unlatching the seat latch; a seatback pivotally attached to the seat cushion via a recliner device, the recliner device including a recliner control device configured to selectively cause the recliner device to be in a first state for locking the seatback in an upright position and a second state for locking the seatback in a stowage position; a first connecting element connecting the recliner device to the seat control device so that the seat latch can be unlatched only when the recliner device is in the second state; and a second connecting element connecting the seat latch to the recliner control device so that the recliner device can take the first state only when the seat latch is fully latched.

First claim

The invention claimed is:

1. A detachable vehicle seat, comprising:
a seat cushion provided with a seat latch for selectively securing the seat cushion to a vehicle body, the seat latch being provided with a seat control device for selectively unlatching the seat latch;
a seatback pivotally attached to the seat cushion via a recliner device so as to be moveable between an upright use position and a folded stowage position, the recliner device being provided with a recliner control device configured to selectively cause the recliner device to be in a first state for locking the seatback in the upright use position and a second state for locking the seatback in the folded stowage position;
a first connecting element connecting the recliner device to the seat control device so that the seat latch can be unlatched only when the recliner device is in the second state; and
a second connecting element connecting the seat latch to the recliner control device so that the recliner device can take the first state only when the seat latch is fully latched,
wherein the recliner control device includes a recliner control member for selectively permitting positioning of the seatback between the upright use position and the folded stowage position, and a recliner blocking member that can be selectively activated so as to prevent the recliner control member from causing the seatback to take the upright use position, and the second connecting element is connected to the recliner blocking member.

2. The detachable vehicle seat according to claim 1 , wherein the upright use position includes a plurality of angular positions of the seatback relative to the seat cushion which can be selected via the recliner device.

3. The detachable vehicle seat according to claim 1 , wherein the seat latch includes a pair of seat latches provided on either side of the seat cushion, and
the seat latches are connected to the recliner control device so that the recliner device can take the first state only when the seat latches are both fully latched.

4. The detachable vehicle seat according to claim 1 , wherein the seat control device includes a seat control member for selectively latching and unlatching the seat latch, and a seat blocking member that can be selectively activated so as to keep the seat control member from unlatching the seat latch, and the first connecting element is connected to the seat blocking member.

5. The detachable vehicle seat according to claim 4 , wherein the seat latch includes a rotatable hook member supported by the seat cushion so as to be rotatable between an engaged position for engaging a striker attached to the vehicle body and a disengaged position for disengaging the striker,
a cam member rotatably supported by the seat cushion so as to be rotatable between a retaining position for retaining the hook member in the engaged position and a release position for releasing the hook member from the engaged position,
a spring member connected between the hook member and the cam member so as to urge the hook member toward the engaged position and the cam member toward the retaining position; and
an unlatching control member connected to the cam member so as to rotate the cam member toward the release position when the unlatching control member is pulled.

6. The detachable vehicle seat according to claim 5 , wherein the first connecting element comprises a first control cable connected between the seat blocking member and the recliner device, and the second connecting element comprises a second control cable connected between the seat latch and the recliner blocking member.

7. The detachable vehicle seat according to claim 6 , wherein at least one of the first control cable and the second control cable includes a tension compensator.

8. The detachable vehicle seat according to claim 1 , wherein the seat control device and the recliner control device each include an electrical actuator, and the first connecting element and the second connecting element comprise electric wires.

9. A method of assembling a detachable vehicle seat, comprising:
providing a seat cushion and a seatback pivotally attachable to the seat cushion;
attaching the seatback to the seat cushion via a recliner device which can be in a first state for locking the seatback in an upright use position and a second state for locking the seatback in a folded storage position selectively, so that the seatback can move between the upright use position and the folded storage position;
providing a recliner control device including a recliner control member and a recliner blocking member with the recliner device, the recliner control member selectively permits positioning of the seatback between the upright use position and a folded stowage position and the recliner blocking member can be selectively activated so as to prevent the recliner control member from causing the seatback to take the upright use position;
providing a seat latch with the seat cushion for selectively securing the seat cushion to a vehicle body;
providing a seat control device with the seat latch for selectively unlatching the seat latch;
connecting the recliner device to the seat control device by a first connecting element so that the seat latch can be unlatched only when the recliner device is in the second state; and
connecting the seat latch to the recliner blocking member by a second connecting element so that the recliner device can take the first state only when the seat latch is fully latched.
