Embodiment Construction

[0057] Vehicle Seat 1 According to figure 1 There is a seat cushion (seat part) 2 with a seat part side 2a and a backrest 3 with a backrest side 3a. Can be provided with at seat cushion 2 and / or backrest 3 place and be used for figure 2 with 3 The adjustment at the seat occupant 5 shown in or the matching adjustment device 4 . The figures show the corresponding configuration of the adjustment device 4 in the backrest 3 for adjusting the backrest side 3a.

[0058] The adjustment can already take place, for example, when the seat occupant 5 is seated; moreover, it can take place, for example, in critical driving situations and / or in the case of cornering driving and a corresponding inertial load on the seat occupant 5 . In this case, the two lateral backrest sides 3 a are pivoted in the transverse direction, that is to say in the Y direction or in the −Y direction. Adjust device 4 in figure 2 , 3 is shown more precisely and has a left side adjustment device 4a and a right...

Abstract

The invention relates to a pneumatic adjustment device (4) for adjusting a side part (3a) of a vehicle seat from a base position into an actuation position, the adjusting device (4) has a double-armed lever (7) with an outer lever arm (7b) and an inner lever arm (7a) for adjusting the sides (3a), an inflatable blowing device for adjusting the inner lever arm (7a), such as a bubble (10), and a mechanical spring device (9) for adjusting the inner lever arm (7a). According to the invention, the blowing device (10) is filled in a basic position of the adjusting device (4), the spring device (9) is tensioned in the basic position and pretensions the inner lever arm (7a) into the actuation position, and the spring device (9) presses the air bubble (10) in the actuation position, a locking device (12), for example a locking air bubble (18), is provided, the locking device can be adjusted between an unlocking position and a locking position and locks the basic position in the locking position for unloading the blowing device (10).

Description

technical field [0001] The invention relates to an adjustment device for a side portion (Seitenwange, also sometimes called side wall) of a vehicle seat and to such a vehicle seat. Background technique [0002] In the case of a vehicle seat with seat cushion and backrest, the seat occupant is usually accommodated between laterally projecting sides (side bulges), which thus support the seat occupant towards the side. In this case, some vehicle seats make it possible to adapt their sides to the seat occupant. [0003] For this purpose, adjustment devices are provided, for example, in the seat part or the backrest, which enable a lateral inward adjustment of the exterior in order to better accommodate and support the seat occupant laterally. This adjustment can also be used to increase the safety of the seat occupant in hazardous or critical driving situations. Thus, by adjusting the sides, for example when driving through a curve, better support of the seat occupant against ...
