A vehicle seat device includes: a seat body including a seat cushion and a seatback; at least a pair of airbag modules provided as a left-right pair at left and right side portions of the seat body; and a moveable section that supports the airbag module and is movable with respect to the seat body, wherein the airbag modules are moved, by movement of the moveable section, between first positions along side portions of the seat body, and second positions in front of a front face of the seatback, and airbags deployed from the airbag modules in the second position sandwich an occupant seated in the seat body between the airbags and the seatback.

Claims

1. A vehicle seat device comprising:

a seat body including a seat cushion and a seatback;

at least a pair of airbag modules provided as a left-right pair at left and right side portions of the seat body; and

a moveable section that supports the airbag module and is movable with respect to the seat body, wherein

the airbag modules are moved, by movement of the moveable section, between first positions along side portions of the seat body, and second positions in front of a front face of the seatback, and

airbags deployed from the airbag modules in the second position sandwich an occupant seated in the seat body between the airbags and the seatback.

2. The vehicle seat device of claim 1, wherein

the moveable section is capable of moving with respect to the seat body so as to make the second position adjustable in at least one of distance of the second position from the seat cushion, or distance of the second position from the seatback.

3. The vehicle seat device of claim 2, further comprising:

a drive section that moves the moveable section; and

a controller that sets the second position based on physique data according to the physique of an occupant seated in the seat body, and controls the drive section such that the airbag modules are disposed in the set second position.

4. The vehicle seat device of any one of claim 1, further comprising:

a drive section that moves the moveable section; and

a controller that detects an occupant sitting in the seat body based on sitting data according to the seated state of the occupant in the seat body, and controls the drive section so as to dispose the airbag module in the second position when an occupant sitting in the seat body has been detected.

5. The vehicle seat device of any one of claim 1, further comprising:

a drive section that moves the moveable section; and

a controller that controls the drive section so as to dispose the airbag module in the second position when a vehicle collision has been predicted by a collision prediction system.
