7. The forklift according to claim 5, wherein said arm rest is pivotally mounted to said seat and rotation of said seat into said third position is permitted by pivoting said arm rest.

8. The forklift according to claim 1, wherein there is provided a locking mechanism for releasably locking rotation of said seat in at least one position.

9. The forklift according to claim 8, wherein there is provided a release device for releasing said locking mechanism and allowing rotation of said seat.

10. The forklift according to claim 1, wherein a sitting surface of said seat tapers in a direction away from a backrest of said seat.

11. The forklift according to claim 1, wherein there is provided another safety bracket on the other side of said seat.

12. The forklift according to claim 1, wherein there is provided a rotation drive for rotating said seat.

13. The forklift according to claim 1, wherein said safety bracket is rigidly mounted to a mounting platform of said seat.

14. The forklift according to claim 1, wherein said safety bracket is pivotably mounted relative to said seat.

15. The forklift according to claim 1, wherein rotation of said seat is mechanically biased by way of a spring device in one of the rotational directions of said seat.

DETAILED DESCRIPTION OF THE INVENTION

[0026] The figures show a truck-mounted forklift 1 having a cabin 2 and a seat 3 for use by a driver arranged in the cabin 2.

[0027] The cabin 2 has a lateral opening 4 to enter and exit the cabin 2. The seat 3 is mounted rotatably relative to the cabin 2.

[0028] There is provided a safety bracket 5 for preventing a driver from involuntarily exiting the cabin 2 through the lateral opening 4 and for providing lateral impact protection. According to the invention the safety bracket 5 is mechanically connected to the seat 3 to be rotatable together with the seat 3. The safety bracket 5 can be used as a handgrab by the driver when entering the cabin 2.

[0029] The safety bracket 5 rotates together with the seat 3 in an upright position. The safety bracket 5 extends from the sitting surface 7 of the seat 3, or more specifically from the seat mounting frame 9 under the seat 3, to an upper end of the backrest 8 of the seat 3 and in the shown embodiment extends for a distance beyond the upper end of the backrest 8.

[0030] In the shown embodiment mechanical coupling is being done by rigidly mounting both the seat 3 and the safety bracket 5 on a mounting frame 9 (with the possible exception of slidably moving the seat 3 along the mounting frame 9 in order to adjust distance between seat 3 and a forward end of the cabin 2 where driving controls are arranged, however the safety bracket 5 does not have to be slidably mounted to the mounting frame 9). The mounting frame 9 is rotatable relative to the cabin 2 and can be releasably locked by a locking mechanism in two different positions: [0031] a first position in which entry and exit of the cabin 2 is facilitated [0032] a second position in which the seat 3 is oriented substantially in a forward driving position looking towards a driving wheel 11 and pedals 12 (note that in the shown embodiment the forward driving position the seat 2 is oriented with an angle about 5 relative to the forward driving direction of the forklift 1).

[0033] It would also be feasible to provide a third position in which the seat 3 is oriented suitable for rearward driving.

[0034] In an alternative embodiment, the seat 3 and the safety bracket 5, which are mechanically connected, part rotatably to the mounting frame 9.

[0035] In the shown embodiment the seat 3 has to be rotated by the driver without support by a rotation drive except for a spring device which biases the mounting frame 9 in rotation direction from the second to the first position. A release lever 10 releases a locking mechanism which locks rotation of the mounting frame 9 in the first and second position. The locking mechanism can comprise a cam that can be swivelled against the force of a spring by the release lever 10. In the shown embodiment the release lever 10 is arranged on the left side of the seat 3 (cf. FIG. 5a) although it could be positioned elsewhere. The shown placement minimizes danger of accidentally opening the locking mechanism. By way of example, to release the seat 3 in the second position it has to be pushed rearward to be rotatable into the first position (rearward motion to enable outward rotation is a natural movement for a driver). A release of the seat 3 in the second position by pushing the release lever 10 in the opposite, forward position for the seat 3 to be rotatable into the first position can also be envisioned.

[0036] To increase comfort for the driver there is provided an arm rest 6 for the seat 3 (cf. FIG. 5b). The arm rest 6 is pivotally mounted to the seat 3. In FIG. 5b rotation of the seat 3 into a third position for rearward driving is permitted by pivoting the arm rest 6 (in the shown embodiment by pushing the arm rest 6 outward, i.e. away from the sitting surface 7 of the seat 3).

[0037] As shown in FIGS. 5a and 5b the seat 3 can be provided with a seat belt.

[0038] There might be provided a sensor detecting the swivel position of the seat 3 in order to only allow driving of the forklift 1 if the seat 3 is in forward driving position.
