Embodiment Construction

[0047] Figure 1a is a perspective view of a vehicle seat 1 (and representing a vehicle cabin C) according to the invention, having a vehicle seat length direction 1x, a vehicle seat width direction 1y and a vehicle seat height direction 1z. The seat comprises an upper part 2 and a lower part 3, in this case by two height-adjustable scissor action frames 4 (cf. figure 2 ) are spring mounted relative to each other. The scissor action frames 4 face each other in the vehicle seat width direction 1 y such that one scissor action frame 4 is arranged on the left and right sides of the vehicle seat 1 , respectively.

[0048] It should be noted that the following description refers to a vehicle seat 1 and its upper part 2 and lower part 3 . It is also conceivable that the cab C comprises an upper part and a lower part as will be described.

[0049] The vehicle seat 1 is characterized by a height adjustment device 17 for the scissor action frame 4 comprising a manually actuatable le...

Abstract

The present invention involves a vehicle cab or vehicle seat, including the upper and lower part of the vertical spring installation through the upper and lower parts of the vertical spring through at least one height and adjustable shear.The two scissors arm and at least one air spring with variable air volume. The movement of the shear framework is mechanically connected to the transmission element of the shear framework to the switch elementThe height adjustment device for the shear framework includes the control lever element that can manually operate and the guide element connected to the control rod component mechanically.In the direction of the switching element, the first rotation axis is rotated in order to change the middle position between the two switches set by the air volume of the switching element to control the air spring.

Description

technical field [0001] The invention relates to a vehicle cab or a vehicle seat comprising a height adjustment device. Background technique [0002] Vehicle cabins or vehicle seats used in particular in commercial vehicles often have to meet many of today's requirements. In particular, they should offer the vehicle occupants as much comfort and a high level of personal adjustment options as possible. For this purpose, many commercial vehicle seats are provided, for example, between the upper and lower parts with a height-adjustable scissor-action frame comprising two scissor arms and a pneumatic vertical suspension. However, the following description applies equally to the upper and lower parts of the vehicle cab. [0003] It is generally known to arrange compressed air springs on the scissor action frame such that they are arranged, for example, between two scissor arms or between one of the scissor arms and the lower part and are supported on the scissor action frame. T...
