Title: SEAT ADJUSTMENT MECHANISM
Abstract:
A combined height and tilt adjustment mechanism (10) for a vehicle seat which enables separate adjustment of the height of a forward part of the seat and an aft part of the seat, thereby enabling independent height and tilt adjustment of the seat. The mechanism comprises: a forward crank (40) for coupling to a seat base (15) and adapted to displace the forward part of the seat base in a substantially vertical direction by rotation of the forward crank about a first axis (34, 35), said forward crank being coupled to a first linear positioning device (70) for releasably locking the position of said forward crank; and an aft crank (50) for coupling to the seat base (15) and adapted to displace the aft part of the seat base in a substantially vertical direction by rotation of the aft crank about a second axis (36, 37), said aft crank being coupled to a second linear positioning device (80) for releasably locking the position of said aft crank.
