摘要:
A height adjuster for a vehicle seat and a vehicle seat incorporating such an adjuster is disclosed. The adjuster includes a plurality of rotary (preferably, planetary) gearboxes (64,66) to regulate the height of a seat frame (62). Embodiments are disclosed that use two of such gearboxes and that use four of such gearboxes. The gearboxes may be mounted on a slide (60) associated with the seat. In such embodiments, the gearboxes may have a lift arm (32) connected to the frame (62) optionally through a link (46). In alternative embodiments, the gearbox is carried on the seat frame and connected to the slide through a lift arm. The seat frame (62) may be further supported by a pivotable link to effect raising and lowering of the frame (62).

In an arrangement for a seat (2) in a vehicle, the seat is movable in a longitudinal direction along a plane (33) which slopes relative to the horizontal plane. The subframe of the seat (2) consists of devices (30, 31) fastened respectively to the vehicle and to the seat, which devices consist of two substantially similar triangular supporting frames. Resetting between a predetermined driving position and a likewise predetermined resting position is made possible by a control device (16) which is fastened to the device (30) which is itself fastened to the vehicle, which control device cooperates with a locking device fastened to the seat so that during a relocating movement between forward and rear positions of the seat the locking device (17) becomes free from at least one locking position between the vehicle seat and the device (30) fastened to the vehicle.

The invention relates to a steering post for a work machine, comprising a steering platform mounted on the frame of the machine and a seat connected to the steering platform by means of a seat leg. To speed up the adjustability of the seat a tubular member (9) is connected to the steering platform in a substantially vertical position, and the seat leg (8) and the tubular member (9) are fitted at least partly within each other and secured in their place by means of bearings (11) so that the seat leg (8) can move vertically in relation to the tubular member (9) and that the seat leg (8) may pivot about its longitudinal axis (12) by the action of a torque reaching or exceeding a given magnitude by turning the bearings (11) a corresponding degree in their fastening.

A mechanism for adjusting the height of a vehicle seat (13) comprises a pair of front and rear bell cranks (16, 19) pivotted on a fore and aft seat slide (12) at each side of the seat. One end (15, 18) of each crank is pivotted to the front or rear of the seat and the other ends (23, 24) are interconnected by a link (23). Height adjustment is achieved by turning one of the cranks by a handle (31).
