Abstract
Official abstract text for this publication.
A vehicle seat device includes a fixed base, a movable base, a paddle, and an air pack. When a side airbag arranged in the seat is deployed, the expanding side airbag presses and pivots the movable base and allows for a deployment of the side airbag. The paddle is configured to change a seat support form when pressed and pivoted by the air pack. The movable base pivots about a first pivot axis relative to the fixed base. The paddle pivots about a second pivot axis relative to the movable base. The first pivot axis and the second pivot axis are arranged at different locations.
First claim
Opening claim text (preview).
The invention claimed is: 1. A vehicle seat device, comprising: a fixed base fixed to a structural body of a seat; a movable base pivotally coupled to the fixed base; a paddle pivotally coupled to the movable base; and an air pack inflated and deflated between the movable base and the paddle, wherein when a side airbag arranged in the seat is deployed, the expanding side airbag presses and pivots the movable base and allows for a deployment of the side airbag, the paddle is configured to change a seat support form when pressed and pivoted by the air pack, the movable base pivots about a first pivot axis relative to the fixed base, the paddle pivots about a second pivot axis relative to the movable base, and the first pivot axis and the second pivot axis are arranged at different locations. 2. The vehicle seat device according to claim 1 , wherein the second pivot axis is arranged at a location closer to a distal end of the movable base than the first pivot axis. 3. The vehicle seat device according to claim 1 , further comprising: a biasing member; wherein the biasing member biases the movable base in a direction opposite to a direction in which the side airbag presses and pivots the movable base. 4. The vehicle seat device according to claim 3 , wherein the biasing member is a torsion coil spring that is arranged coaxially with the first pivot axis. 5. The vehicle seat device according to claim 3 , wherein the movable base is held by a biasing force of the biasing member at a location contacting the fixed base.
