Abstract
The present invention is a seat bottom suspension system adapted to provide a varying spring constant. An embodiment includes a first plurality of generally flat elongated biasing members in communication with an axle adapted to translate in a direction generally parallel with the longitudinal axis of the biasing members. An embodiment may include a second set of flat elongated biasing members set at a lower height than the first plurality of flat elongated biasing members to provide a progressive increase in the spring constant as the down force seen on the seat increases.
Claims17
A seat suspension system, comprising:
- a seat bottom having at least two separated, parallel walls with an open cavity established therebetween;
- at least one biasing member disposed within the open cavity, wherein the biasing member further includes:
- a first end, a second end, and a fixed length extending therebetween;
- the first end located near one of the walls;
- and
- an axle located near the second wall, the axle having a length extending generally perpendicular in relation to the elongated biasing member and a set of guides extending in a perpendicular direction to secure the elongated biasing member to a set location along the length of the axle when the elongated biasing member passes through the set of guides.
A seat suspension system, comprising:
- a seat bottom having at least two separated, parallel walls with an open cavity established therebetween;
- at least one biasing member disposed within the open cavity, wherein the biasing member further includes:
- a first end, a second end, and a fixed length extending therebetween;
- the first end located near one of the walls;
- an axle disposed in a generally perpendicular relation with respect to the biasing member and secured within the open cavity, the axle adapted to translate in a direction perpendicular to the axle;
- and
- the second end of the biasing member in mechanical communication with the axle;
- and
- the axle having a first resting location that is closer to the first end of the elongated biasing member and a second resting location of the axle closer to the second end of the elongated biasing member, such that the elongated biasing member includes a greater spring constant when the axle is located at the first resting location closer to the first end of the elongated biasing member than when the axle is located at the second resting location closer to the second end of the elongated biasing member.
