Vehicle vibration device for vehicle seats or vehicle cabs

摘要

The invention concerns a vehicle vibration device for a vehicle seat or a vehicle cab with a lower part and an upper part sprung mounted in relation to the lower part by at least one damper device, wherein the upper part is mounted suspended on the lower part so that on occurrence of vibrations between the upper part and lower part, the upper part can swivel about a fictitious or real axis arranged below the upper part and extending in the vehicle width direction or vehicle length direction.

主权项

1. A vehicle seat, comprising:
a lower part; an upper part mounted in relation to the lower part by at least one damper device, wherein the upper part is mounted to and suspended on the lower part so that the upper part is configured to pivot about a virtual axis arranged below the upper part and extending in a width direction or a length direction; a first plurality of lever arms including, at least, a first lever arm and a second lever arm, wherein a first end of the first lever arm of the first plurality of lever arms is attached to the lower part at a first swivel axis, wherein a second end of the first lever arm of the first plurality of lever arms is attached to the upper part at a third swivel axis, wherein a first end of the second lever arm of the first plurality of lever arms is attached to the lower part at a second swivel axis, wherein a second end of the second lever arm of the first plurality of lever arms is attached to the upper part at a fourth swivel axis, and wherein for each of the first and second lever arms of the first plurality of lever arms, the second end lies below the first end; a base, the base including a front wall and a rear wall; a second plurality of lever arms including, at least, a first lever arm and a second lever arm, wherein a first end of the first lever arm of the second plurality of lever arms is attached to the base at a fifth swivel axis, wherein a second end of the first lever arm of the second plurality of lever arms is attached to the lower part at a seventh swivel axis, wherein a first end of the second lever arm of the second plurality of lever arms is attached to the base at a sixth swivel axis, wherein a second end of the second lever arm of the second plurality of lever arms is attached to the lower part at an eighth swivel axis, and wherein for each of the first and second lever arms of the second plurality of lever arms, the second end lies below the first end, a curved track arranged on the lower part, wherein the third swivel axis is configured to slide within the curved track arranged on the lower part, and wherein the curved track defines a maximum possible swivel movement of the upper part relative to the lower part; and wherein the front and rear walls of the base define a space in between, and wherein the lower part is suspended within the space in between the front and rear walls.
