Abstract
The present disclosure provides a damper system for a suspension of a vehicle seat. A linkage of the damper system can be configured to cause a damper to provide different damping characteristics when the suspension moves towards a neutral position than when the suspension moves away from the neutral position.
Claims20
A suspension for a vehicle seat, to move a seat portion of the vehicle seat relative to a neutral position, the suspension comprising:
- a damping linkage coupled between a base of the suspension and a suspension member that is configured to support the seat portion of the vehicle seat relative to the base;
- and
- a damper coupled between the base and the damping linkage;
- the damping linkage comprising a first damping link, a second damping link, and an intermediate damping link, with:
- the first damping link coupled between the base and the damper;
- and
- the second damping link arranged between the suspension member and the intermediate damping link;
- and
- the intermediate damping link pivotally coupled between the second damping link and the damper;
- wherein the first, second, and intermediate damping links cooperate to actuate the damper in a first direction when the suspension is moved in an upward direction away from the neutral position and when the suspension is moved in a downward direction away from the neutral position.
A suspension for a vehicle seat, to move a seat portion of the vehicle seat upward and downward relative to a neutral position, the suspension comprising:
- a damper configured to provide damping primarily when moved in a first direction corresponding to extension or compression of the damper;
- and
- a linkage secured to the damper and configured to be secured between a support member of the suspension and a base of the suspension;
- the linkage being configured to cause the damper to move in the first direction when the seat portion is moved upward from the neutral position and when the seat portion is moved downward from the neutral position.
A suspension for a vehicle seat, to move a seat portion of the vehicle seat in an upward and downward direction relative to a neutral position, the suspension comprising:
- a linkage coupled between a base and a movable suspension member of the suspension, the linkage comprising:
- a first damping link, a second damping link, and an intermediate link;
- the first damping link being pivotally coupled to the base and to an end of a damper;
- and
- the second damping link being coupled to the movable suspension member of the suspension and to the intermediate link;
- wherein the intermediate link is pivotally coupled to the second damping link and to the end of the damper;
- and
- wherein the first damping link is configured to pivot in a first rotational direction to actuate the damper in a first direction when the suspension is moved away from the neutral position.
