Abstract

A vehicle seat device comprises: a seat disposed at a vehicle width direction inner side of a side door of a vehicle; a rotating mechanism that rotates the seat about a vertical axis relative to a vehicle body; a sideways movement mechanism that moves the seat in a vehicle width direction relative to the vehicle body between a normal region and an inner region; and a control device which, when causing the rotating mechanism to rotate the seat, causes the sideways movement mechanism to move the seat from the normal region to the inner region before the rotation.

Claims

1. A vehicle seat device, comprising:

a seat disposed at a vehicle width direction inner side of a side door of a vehicle;

a rotating mechanism that rotates the seat about a vertical axis relative to a vehicle body;

a sideways movement mechanism that moves the seat in a vehicle width direction relative to the vehicle body between a normal region, in which the seat is normally disposed and in which rotation about the vertical axis is limited because of interference between the side door in a closed state and the seat, and an inner region, which is set at a vehicle width direction inner side of the normal region and in which the seat is rotatable about the vertical axis without interfering with the side door in a closed state; and

a control device which, when causing the rotating mechanism to rotate the seat, causes the sideways movement mechanism to move the seat from the normal region to the inner region before the rotation.

2. The vehicle seat device according to claim 1, further comprising:

an obstacle disposed at a vehicle width direction inner side of the seat positioned in the normal region; and

an obstacle movement mechanism that moves the obstacle out of a rotational region of the seat,

wherein the control device causes the obstacle movement mechanism to move the obstacle out of the rotational region before causing the sideways movement mechanism to move the seat from the normal region to the inner region.

3. The vehicle seat device according to claim 1, further comprising:

a forward and rearward movement mechanism that moves the seat in forward and rearward directions relative to the vehicle body and which has forward and rearward direction reference positions set in a movement range of the forward and rearward directions; and

a reclining mechanism that tilts a seat back of the seat relative to a seat cushion of the seat and which has an inclination reference position set in a tilting range of the seat back,

wherein the control device causes the forward and rearward movement mechanism to move the seat to the forward and rearward direction reference positions and causes the reclining mechanism to move the seat back to the inclination reference position before causing the sideways movement mechanism to move the seat from the normal region to the inner region.

4. The vehicle seat device according to claim 2, further comprising:

a forward and rearward movement mechanism that moves the seat in forward and rearward directions relative to the vehicle body and which has forward and rearward direction reference positions set in a movement range of the forward and rearward directions; and

a reclining mechanism that tilts a seat back of the seat relative to a seat cushion of the seat and which has an inclination reference position set in a tilting range of the seat back,

wherein the control device causes the forward and rearward movement mechanism to move the seat to the forward and rearward direction reference positions and causes the reclining mechanism to move the seat back to the inclination reference position before causing the sideways movement mechanism to move the seat from the normal region to the inner region.
