Adjustable seat device for a vehicle, comprising: -a base portion (), -a seat portion () that is movable with respect to the base portion () between a first position, referred to as retracted, and a second position, referred to as extended, -an articulation system () forming a deformable parallelogram, which is connected to the base portion () and to the seat portion () and comprises at least one diagonal support arm () connected diagonally to the deformable parallelogram, characterized in that the diagonal support arm () is designed to have a first length when the seat portion () is in the first position and a second length when the seat portion () is in the second position.

Adjustable-height seat device

An active bolt release arrangement includes a nut having nut portions adapted for radial movement, a sleeve part encircling the nut and having contact portions in contact with the nut portions in order to prevent the nut portions from radial movement, and a pyrotechnical actuator. The pyrotechnical actuator is adapted for, upon deployment, moving the sleeve part relative to the nut to a released position forming a release space allowing radial movement of the nut portions. The pyrotechnical actuator is arranged for turning, upon deployment, the sleeve part a predetermined rotational distance to the released position, such that radial movement of the nut portions by formation of the release space is allowed, thereby causing release of a bolt connected to the bolt release arrangement.

Active bolt release arrangement

An adjustable seat () incorporates a moveable squab element (). The squab element may be moved from an initial position in which the squab element is flush with the remaining parts of the vehicle seat to a first intermediate position and then to a subsequent second position. The squab is mounted on a first linkage () which carries an intermediate support. A second linkage () extends from the intermediate support to a seat mount () incorporated with the squab element.
