Problems solved by technology
Due to the aforementioned reasons, such as the degrees of freedom required for good movement, the largest possible support surface can only be achieved under certain conditions, thus leading to an unsatisfactory realization, due to the fact that the driver is between two completely different operating positions. Alternate between
[0009] Another major drawback is that the possible swivel range of the swivel adapter is limited because the pedals and steering wheel are still required to safely control the utility vehicle even while looking at the operating equipment at the rear
In order to meet these demands, the driver is often forced to assume uncomfortable positions for considerable lengths of time, which necessarily results in dangerous contortions of his / her entire body
Furthermore, scientific studies have proven that such uncomfortable postures, especially when there are vibrations, can damage the body structure, especially if the body is not well supported

Embodiment Construction
[0161] Figure 1 to Figure 8 The vehicle seat 1 shown in is a multipurpose motor vehicle seat 1A. The multipurpose motor vehicle seat 1A comprises a seat part 2 , a backrest 3 , an armrest 5 which is further arranged on a right side 4A of the backrest 3 .
[0162] The seat part 2 of the utility vehicle seat 1A is connected to the body (not shown) of the utility vehicle 6 via a lower vehicle seat part (not shown).
[0163] The utility vehicle 6 defines a vehicle longitudinal extension X, a vehicle transverse extension Y and a vehicle vertical extension Z, which can also be used to indicate the orientation of the utility vehicle seat 1A.
[0164] Thus, using the longitudinal extension X it is possible to define a "front" or "rear" position or a change in position of the backrest 3 .
[0165] With the aid of the transverse vehicle extension Y, a position or a change in position “transversely” or “towards the side” relative to the backrest 3 can be defined.
[0166] Accordingly...

The invention relates to a vehicle seat (1), in particular a utility motor vehicle seat (1 A), having a seat part (2), having a backrest (3) comprising a lower backrest part (16) and an upper backrest part (17), and having a holding device (25), by means of which the upper backrest part (17) is mounted displaceably with respect to the lower backrest part (16), wherein the holding device (25) comprises a guide device (26), by means of which the upper backrest part (17) can be linearly displaced along a displacement curve (27) laterally past at least one side edge (4A, 4B) of the lower backrest part (16) in such a way that the upper backrest part (17) can also be rotated about the displacement curve and / or about a transverse axis (35) extending in a transverse manner to the displacement curve (27) during the lateral displacement.
Description
technical field [0001] The present invention relates to a vehicle seat, in particular to a multi-purpose motor vehicle seat comprising a seat part, a backrest part and a holding device, wherein the backrest part comprises a lower backrest part and an upper backrest part, the The upper backrest part is movably mounted relative to the lower backrest part via the support device. [0002] The invention also relates to a utility vehicle, in particular an agricultural utility vehicle, comprising at least one seat. Background technique [0003] A variety of conventional vehicle seats, especially for utility motor vehicles, especially for agricultural utility vehicles, are well known in the prior art. [0004] Especially for the drivers of these agricultural multipurpose motor vehicles, they often adopt a horizontal or backward working sitting posture in the process of utilizing these agricultural multipurpose motor vehicles and the work equipment connected thereto, which is differ...
