Abstract: A transportation vehicle is disclosed, including front frame and rear frame. The front frame and rear frame are hinged together and the rear frame can swing left and right with respect to the front frame; the two sides of the front frame are provided with two wheel hub axles, and the driven wheels are connected to the front frame through the wheel hub axles; the rear frame is provided with a vertically configured connecting rod; the connecting rod is flexibly connected to the middle portion of the first push-pull rod, and the two ends of the first push-pull rod can swing up and down; the two ends of the first push-pull rod are respectively connected to the wheel hub axles through the rocker arm connecting rod mechanism. Through configurations of the first push-pull rod, wheel hub axles and rocker arm connecting rod mechanisms, when the transportation vehicle is making a turn, the gravity component of the human body and vehicle can offset the centrifugal force generated by the human body and vehicle.

Abstract: A method for assembling a case (5), such as integral play station, a simple screen for a DVD reader or for a play station, a loudspeaker, on a cushion (2) such as a headrest or a set back cushion, fitted with a protection cover (4) includes fastening the case (5) directly on the protection cover (4), before mounting the cover (4) on the cushion (2).

Abstract: The invention concerns a case (1) consisting of two storage parts (4, 5) mutually secured via a hinge system and provided with means (7) for being removably locked in closed position, that is when they are in contact with each other through their peripheral edge. One of the storage parts (5) is adapted to receive detachably a video screen (3) with its front face visible when the case is in opened position, the other storage part (4) is adapted to receive the electronic console (2) associated with said screen (3) likewise detachably (said console (2) being for example in the form of a DVD video player or a game console). The case further comprises: at least one powering plug-in connection terminating in two removable plug connectors on the screen (3) and electronic console (2), and an internal wiring system provided with detachable plugs for audio-video connection between said electronic console (2) and said associated video screen (3).

Abstract: A method for assembling a case (5), such an integral play station, a simple screen for a DVD reader or for a play station, a loudspeaker or other . . . , on a cushion (2) such as a headrest or a seat back cushion, fitted with a protection cover (4). This method is characterized in that it consists in fastening the case (5) directly on the protection cover (4), before mounting said cover (4) on the cushion (2).

Abstract: The invention relates to a headrest, particularly for a motor vehicle seat, comprising a cushion made from synthetic foam which houses an integrated support that can be used to fix two parallel anchor rods to the seat. According to the invention, the anchor rods are fitted with threaded shafts that extend at a right angle from the upper end of said rods. The threaded shafts are each screwed into one end of a housing body in the form of a cylindrical sleeve having a suitable internal threading. Tightening locknuts are used to lock the anchor rods in position on the cylindrical sleeve. Said cylindrical sleeve is fixed to a locking lug, which is disposed on the integrated support, by means of a stirrup piece which is associated with a screw-nut type tightening system.
