A vehicle includes: a vehicle body frame; a drive unit provided on the vehicle body frame and movable on a floor surface; a seat disposed above the vehicle body frame to support buttocks of a user; a lift unit provided between the vehicle body frame and the seat to raise and lower the seat between a low position and a high position; and an operation device provided on at least one of a left side portion and a right side portion of the seat. The operation device includes an operation panel having an operation surface that faces upward, a lever extending upward and forward from a rear portion of the operation panel, and multiple operation members provided on the operation surface. At least one of the multiple operation members is disposed in a position overlapping with the lever as seen from above.

A vehicle includes: a vehicle body frame; a drive unit provided on the vehicle body frame and movable on a floor surface; a seat disposed above the vehicle body frame to support buttocks of a user; a lift unit provided between the vehicle body frame and the seat to raise and lower the seat between a low position and a high position; and at least one support member extending downward from the seat and provided, at a lower portion thereof, with a footrest for supporting soles of the user. The support member is provided to be displaceable vertically relative to the seat, and the support member is displaced such that a distance between the seat and the footrest when the seat is in the high position is greater than a distance between the seat and the footrest when the seat is in the low position.

A cover material, in particular a seat cover material, having an upper side and a lower side and at least one seam that runs over at least a part of the cover material and that is visible on the upper side. An electrically conductive element that generates an electric field is arranged on the lower side in the region where the seam runs.

A cover for a switch includes a body having a thru-hole for receiving the switch. Retainers supported by the body each have a groove facing the thru-hole and guide surfaces extending upward from an edge of a bottom surface of the retainers to a lower edge of the groove. The outer surface may be contoured and the contoured outer surface may be oblong. The cover may be used in a switch assembly for a vehicle. The switch has a base extending from a surface of the vehicle and first and second flexible members extending outwardly from the base in a normal position. The guide surfaces deflect the flexible members from a normal position during installation of the cover. The flexible member returns to the normal position when the cover is placed such that an upper portion of the flexible member is retained within the groove.

A control unit system (40) suitable for an aircraft seat (10) comprises a first control unit (42) with first user-operable input devices (44), and a second control unit (46) with second user-operable input devices (48). The first and second control units are co-operable with one another so that, in response to operation of any one of the first user-operable input devices by a user, a corresponding set (48A, 48B, 48C, 48D) of one or more of said second input devices (48) is operated to adopt the activated state. The control unit system allows a relatively high number of functions to be supported without requiring a large control unit. or complex and expensive hardware or software. Moreover, the system is relatively simple to use compared to. for example. a control unit with a large number of user input buttons or a complex human-computer interface.

A seat body for a seat of a motor vehicle includes a support element having a securing surface and a seat cover surface opposite the securing surface, as well as a connecting body receptacle into which a connecting body of a switch device can be inserted, which is held on the support element in the inserted state in such a way that an actuation element secured to the connecting body ends at the seat cover surface. The seat cover surface of the support element is covered by a seat cover, whereby the connecting body receptacle is covered by the seat cover, such that, if the connecting body is inserted into the connecting body receptacle as intended, the actuation element is covered by the seat cover.

Provided is a seat system which can change a surrounding environment of a user including illumination according to the movement of the user's body. A seat system comprises a seat body on which a user can be seated; a plurality of sensors provided on or in the seat body or on a structure arranged around the seat body and configured to detect a touch operation by the user seated on the seat body; an output device configured to output at least one of sound, light, and vibration; and a control device configured to control the output device such that, when one or more of the sensors detect a touch operation, the control device causes the output device to generate a corresponding predetermined output.
