Vehicle seat, and motor vehicle or multipurpose motor vehicle

Abstract

The invention relates to a vehicle seat having a seat part extending in the vehicle lengthwise direction (X) and in the vehicle width direction (Y) and having a backrest part and a seat substructure for cushioning and/or damping at least the seat part with respect to a body of a vehicle , in which the seat substructure comprises at least one horizontal spring device having a first spring part , another spring part which is movable relative thereto and a deformable fluid spring element for cushioning the seat part with respect to the body in the vehicle lengthwise direction (X) and/or in the vehicle width direction (Y), the deformable fluid spring element being arranged with a first connecting region to the first spring part and another connecting region to the other spring part , wherein the deformable fluid spring element is arranged between the two spring parts so as to be deformed solely by these two spring parts upon relative movement of the two spring parts relative to each other.

Description

technical field [0001] The present invention relates to a vehicle seat comprising a seat part extending in the vehicle longitudinal direction and the vehicle transverse direction for seating a passenger, a backrest part for supporting the passenger's back and for suspending and / or reducing at least the seat part relative to the vehicle body. A vibration seat base (seat substrate), wherein the seat base includes at least one horizontal suspension device for suspending the seat part relative to the vehicle body in the longitudinal and / or transverse direction of the vehicle, the at least one horizontal suspension device comprising the vehicle body a side lower part and a seat part side upper part movable relative to the vehicle body side lower part; wherein a connecting device is interactively provided between the seat part side upper part and the body side lower part, the connecting device Including a deformable suspension part used as a first connecting part and a bearing and d...

AI Technical Summary

Problems solved by technology

However, this arrangement results in a very large structure of the horizontal suspension in the springing direction in order to achieve a specific spring characteristic; or it is also possible to use only correspondingly smaller suspension parts

If the latter is chosen, it is often not possible to achieve the required spring characteristics, or the spring characteristics cannot be achieved to a sufficient degree

Furthermore, the spring characteristics, especially of the suspension elements installed in the horizontal suspension, cannot be changed or affected, or not to a sufficient degree; this means that the resulting spring characteristics cannot be set to an optimum
