Abstract

The present invention is related to a vehicle seat that is displaceable along rails in a longitudinal direction (x-direction). It is often desirable to place the seat in a foremost position in order to create space behind the seat in a driving compartment. Conventional seats are often provided with a lever or the like to control a release mechanism, which releases the seat in the x-direction. In order to increase the available space behind the seat further, it is known to provide the seat with a tip-up seat cushion that can be swung into a substantially vertical position. The object of the invention is to create a seat that is simple to displace in order to create space behind the seat. According to the invention, this is achieved by using the action of swinging the seat cushion upwardly for releasing the seat in the x-direction. This function is achieved by providing e.g. a wire or a linkage between the seat cushion and the release mechanism, said wire or linkage being integrated in the seat cushion.

Quick-release vehicle seat

         The present invention is related to a vehicle seat that is displaceable along rails in a longitudinal direction (x-direction). When the seat is not in use, it is often desirable to place the seat in a foremost storage position in order to create space behind the seat in a driving 5 compartment of a vehicle, e.g. when the driver is resting. Conventional vehicle seats are often provided with a lever or the like to control a release mechanism, arranged in connection to the rails, which releases the seat in the x-direction, whereby the seat can be displaced freely along the rails. In order to simplify the displacement of the seat in different situations, it is known to provide the release mechanism with two separate levers for releasing the seat, 10 one that is hand-maneuvered to be used for displacing the seat while sitting in it, and one that is foot-maneuvered to be used for displacing the seat while not sitting in it. Furthermore, in order to increase the available space behind the seat further, it is known to provide the seat with a tip-up seat cushion that can be swung into a substantially vertical position, so that the seat can be displaced as far forwardly as possible. 15

         The object of the invention is to improve known vehicle seats and thereby create a seat that is more convenient and simple to displace in order to create space in a driving compartment while the seat is not in use. According to the present invention, this is achieved by using the action of swinging the seat cushion upwardly for releasing the seat in the x- direction, and the action of folding the seat cushion downwardly to the original position for 20 locking the seat in a usage position. To achieve the described functions, a force transmission arrangement is provided between the seat cushion and the release mechanism, said transmission arrangement can preferably comprise a wire or a linkage integrated in the seat cushion. Furthermore, according to a preferred embodiment of the invention, the seat is loaded with a force, preferably a spring force, that forces the seat either forwardly or 25 backwardly dependent of the direction of the spring force, whereby the seat will automatically take its' storage position as the release mechanism is activated.

         Fig. 1 shows a seat 10 that is displaceable in a longitudinal direction (x-direction) along rails 12 arranged in a floor construction of a vehicle compartment. A release mechanism 16 that releases the seat in the x-direction is arranged in connection to the rails. 30

    The release mechanism is activated by means of a spring loaded lever 19 that can be actuated by a person sitting in the seat in order to displace it. The release mechanism can e.g. comprise a tooth segment that by influence of the spring force acting on the lever 19 is engaged in a cogging 14 provided on one of the rails, whereby said tooth segment is released from engagement on actuation of the lever 19 as...
