Abstract

A vehicle seat mounting device includes a first component for attachment to a vehicle and a second component for attachment to a vehicle seat. The device further includes an arrangement for connecting the first and second components to each other such that the first component and the second component are adjustable relative to each other by pivoting the first component and the second component relative to each other around a substantially vertical geometrical pivot axis. At least one of the first and second components includes a first unit and a second unit which are displaceable relative to each other in a direction parallel to a substantially horizontal plane, and an arrangement for damping a relative displacement motion of the first and second units in the direction so as to reduce horizontal vibrations in the vehicle seat when the device is installed for use in the vehicle.

Claims

1. A vehicle seat mounting device comprising a first component for attachment to a vehicle and a second component for attachment to a vehicle seat, and a means for connecting the first and second components to each other such that the first component and the second component are adjustable relative to each other by pivoting the first component and the second component relative to each other around a substantially vertical geometrical pivot axis, wherein one of the first and second components comprises a first unit and a second unit which are displaceable relative to each other in a direction parallel to a substantially horizontal plane, and a means for damping a relative displacement motion of the first and second units in the direction so as to reduce horizontal vibrations in the vehicle sea when the device is installed for use in the vehicle, and wherein the first unit and the second unit are rectilinearly displaceable relative to each other along a geometrical line intended to be substantially parallel with a fore-and-aft direction of the vehicle, wherein the other of the first and second components comprises a first unit and a second unit, which are rectilinearly displaceable relative to each other along a geometrical line intended to be substantially perpendicular to the fore-and-aft direction of the vehicle.

2. A device according to claim 1, wherein one of either the first unit or the second unit is provided with rolling means for the displacement motion.

3. A device according to claim 1, wherein at least one of the first unit and the second unit is provided with sliding means for the displacement motion.

4. A device according to claim 1, wherein the damping means comprises a damper connecting the first and second units.

5. A device according to claim 4, wherein the damper is adjustable so as to enable adjustment of the stroke length of the damped displacement motion.

6. A device according to claim 4, wherein the damper is a piston/cylinder-member.

7. A device according to claim 1, wherein the damping means is arranged within the device in a space between the first unit and the second unit.

8. A device according to claim 1, wherein in addition to the damping means at least one spring is arranged for taking up forces in the same direction as the damping means.

9. A device according to claim 8, wherein the spring is arranged within the device in a space between the first unit and the second unit.

10. A device according to claim 1, wherein each of the first and second components comprise a set of so the first and second units and the means for damping a relative displacement motion of the first and second units said the first and second units and damping means of the first component being arranged to reduce vibrations in a first direction, and the first and second units and damping means of the second component being arranged to reduce vibrations in a second direction substantially perpendicular to the first direction.

11. A device according to claim 1, wherein the first component comprises additional means for adjustment of the seat relative the vehicle.

12. A device according to claim 11, wherein the additional seat adjustment means is arranged for adjusting the seat backwardly and forwardly in a direction intended to be substantially parallel with the fore-and-aft direction of the vehicle.

13. A device according to claim 11, wherein the additional seat-adjustment means comprises slide rails.

14. A device according to claim 1, wherein the connection means comprises a rotating plate being a part of the second component, and a base plate being a part of the first component, the rotating plate being rotatably supported relative to the base plate.

15. A device according to claim 1, wherein the second component is arranged above the first component such that the first component and the second component overlap with each other when viewed in a vertical direction.

16. A device according to claim 15, wherein the first and second components substantially entirely overlap with each other.

17. An industrial vehicle comprising a vehicle seat mounting device according to claim 1.
