<p>A seat suspension for a vehicle seat, comprising a base (1), a seat support member (2), and a elongate member (3, 4), the elongate member (3, 4) being pivotally connected at a first end to one of the base (1) and the seat support member (2) and in sliding contact at a second end with the other of the base (1) and the seat support member (2), and carrying a ramp (13) angled relative to and extending along the elongate member (3, 4), one of the base (1) and the seat support (2) forming a support body, the seat suspension comprising a spring unit arranged to provide a spring force between the support body and the ramp(13), in which the spring unit comprises a resilient member (12) held between the support body and a sliding member (14) arranged for sliding motion along the ramp (13) and relative to the support member and the resilient member(12), the sliding member (14) being pivotally mounted to the support body, such that sliding the sliding member (14) along the ramp (13) changes both the compression of the resilient member (12) and the effective spring rate of the suspension.</p> |
