A seat cushion extension apparatus includes an extension motor supported on a cushion frame, an extension mounting bracket holding an extension cushion such that the extension cushion is displaceable forward and backward on a seat cushion, and a power transmission unit connecting between the extension motor and the extension mounting bracket. The power transmission unit receives power from the extension motor and moves the extension mounting bracket forward and backward. A slide device is coupled with the extension mounting bracket, and supports the extension mounting bracket such that the extension mounting bracket is slidable forward and backward in the cushion frame. The front-back length of the seat cushion can be freely extended, and limitations in the thickness of a cushion pad or the like are removed.

A polyurethane filter foam is provided herein. The polyurethane filter foam may have improved permeability by having both a small cell and a large cell in a range for maximizing the opening property of the foam. In some instance, this is achieved by specifically configuring and foaming a composition of polyether polyol and methylene diphenyl diisocyanate (MDI) to manufacture the polyurethane foam. The polyurethane foam of the present invention can be manufactured without performing a reticulation process.

A seat adjustment apparatus for mobility includes a seat cushion, wherein, during seat cushion tilting, the front portion of the seat cushion is moved upwards, and the rear portion thereof is moved downwards so that the occupant's lower body is not moved upwards as a whole, and the occupant's feet are not excessively lifted. Accordingly, there is no need for a separate footrest for supporting the occupant's feet, and seating convenience is improved by implementing a stable occupant posture. Furthermore, a tilting bar provided for seat cushion tilting supports a seat frame so that the posture of the occupant's lower body does not collapse due to deformation of the seat cushion during a collision, securing the occupant's stability.

A seat adjustment apparatus for a vehicle includes: a set bracket having a rear part to which a back frame is rotatably connected; and a cushion frame disposed on an upper side of the set bracket and to be tilted by a link mechanism. In particular, the link mechanism includes: a first link member which is hinge-engaged with a front part of the set bracket, connected to a driving unit and supports a front part of the cushion frame to make the front part of the cushion frame ascend and descend by the driving unit; a second link member hinge-engaged with a rear part of the set bracket and the cushion frame to guide the rear part of the cushion frame; and a third link member hinge-engaged with the set bracket and the cushion frame to determine a tilting position of the cushion frame when the cushion frame ascends.

A headrest device comprises a fixed bracket fixed at a headrest stay and having a driving portion. A first link bracket is connected to the driving portion and a headrest panel which is connected to a headrest cushion, thus the first link bracket moving forward upon actuation of the driving portion. A second link bracket is rotatably connected to the headrest panel and the fixed bracket, respectively, and the first link bracket is connected to the second link bracket. When the first link bracket moves forward, the second link bracket rotatably moves forward together with the first link bracket, thereby tilting the headrest cushion and at the same time moving forward.
