Abstract
Official abstract text for this publication.
A vehicle seat apparatus includes a seat portion, a seatback arranged on a rear side of the seat portion, a seat portion supporting mechanism that supports the seat portion such that a right side and a left side of the seat portion are able to move relative to one another in a vertical direction of the vehicle seat apparatus, and a seat portion restoring force generating mechanism that generates a restoring force that returns the seat portion to an original position when the seat portion rotates.
First claim

The invention claimed is: 1. A vehicle seat apparatus comprising: a seat portion; a seatback arranged to a rear of the seat portion; a seat portion supporting portion that supports the seat portion such that a right side and a left side of the seat portion are able to move relative to one another in a vertical direction of the vehicle seat apparatus; and a seat portion restoring force generating mechanism that generates a restoring force that returns the seat portion to an original position when the seat portion moves; a seatback supporting portion that supports the seatback such that a right side and a left side of the seatback are able to move relative to one another in a vertical direction of the vehicle seat apparatus; and a seatback restoring force generating mechanism that generates a restoring force that returns the seatback to an original position when the seatback moves; wherein the seatback supporting portion supports the seatback such that the right side and the left side of the seatback move relative to one another in a longitudinal direction of the vehicle seat apparatus, and the seat portion restoring force generating mechanism is an elastic member that is connected to the seat portion and a non-moving portion that supports the seat portion. 2. The vehicle seat apparatus according to claim 1 , wherein the seat portion supporting portion rotatably supports the seat portion. 3. The vehicle seat apparatus according to claim 1 , wherein the seat portion supporting portion supports the seat portion such that the right side and the left side of the seat portion move relative to one another in a longitudinal direction of the vehicle seat apparatus. 4. The vehicle seat apparatus according to claim 1 , wherein a rotational axis of the seat portion, which extends from the seat portion supporting portion, is higher at a rear than at a front in a longitudinal direction of the vehicle seat apparatus. 5. The vehicle seat apparatus according to claim 1 , wherein a rotational axis of the seat portion, which extends from the seat portion supporting portion, passes through an area near a chest of an occupant seated in the vehicle seat apparatus. 6. A vehicle seat apparatus comprising: a seat portion; a seatback arranged to a rear of the seat portion; a seat portion supporting portion that supports the seat portion such that a right side and a left side of the seat portion are able to move relative to one another in a vertical direction of the vehicle seat apparatus; and a seat portion restoring force generating mechanism that generates a restoring force that returns the seat portion to an original position when the seat portion moves; a seatback supporting portion that supports the seatback such that a right side and a left side of the seatback are able to move relative to one another in a vertical direction of the vehicle seat apparatus; and a seatback restoring force generating mechanism that generates a restoring force that returns the seatback to an original position when the seatback moves; wherein the seatback supporting portion supports the seatback such that the right side and the left side of the seatback move relative to one another in a longitudinal direction of the vehicle seat apparatus, and the seatback restoring force generating mechanism is an elastic member that is connected to the seatback and a non-movable member that supports the seatback. 7. The vehicle seat apparatus according to claim 6 , wherein the seat portion restoring force generating mechanism is an elastic member that is connected to the seat portion and a non-moving portion that supports the seat portion. 8. The vehicle seat apparatus according to claim 6 , wherein the seat portion supporting portion rotatably supports the seat portion. 9. The vehicle seat apparatus according to claim 6 , wherein the seat portion supporting portion supports the seat portion such that the right side and the left side of the seat portion move relative to one another in a longitudinal direction of the vehicle seat apparatus. 10. The vehicle seat apparatus according to claim 6 , wherein a rotational axis of the seat portion, which extends from the seat portion supporting portion, is higher at a rear than at a front in a longitudinal direction of the vehicle seat apparatus.
