Seat adjuster
First Claim
1. A seat adjuster for adjusting the position of a seat having a seat pan, comprising:
- parallel first and second base members (2, 2a);
spaced first and second rod members (11,
10), each being rotatably supported by said base members;
first and second link mechanisms (7, 7a) respectively connected to spaced portions of said first rod member and mounting thereon a first part of said seat pan, said first and second link mechanisms raising said first part of the seat pan when said first rod member is rotated about its axis in a given direction;
third and fourth link mechanisms (7b, 7c) respectively connected to spaced portions of said second rod member and mounting thereon a second part of said seat pan, said third and fourth link mechanisms raising said second part of the seat pan when said second rod member is rotated about its axis in a given direction;
first and second drive mechanisms (9,
8) mounted to spaced portions of said first base plate for rotating said first and second rod members respectively, each drive mechanism having a one-way clutch function which locks parts of said drive mechanism when a torque is applied thereto from the associated rod member; and
a first sector gear (22) secured to said first rod member for synchronous rotation therewith, said first sector gear having teeth (22b) directed toward said first drive mechanism (9) and operatively engaged with the same, andwherein said first drive mechanism (9) is disposed between said sector gear (22) and said second drive mechanism (8).

Abstract
A seat adjuster is disclosed, which comprises a seat pan; parallel first and second base members; spaced first and second rod members, each being rotatably supported by the base members; first and second link mechanisms respecitvely connected to the first rod member and mounting thereon a front part of the seat pan, the first and second link mechanisms raising the front part of the seat pan when the first rod member is rotated about its axis in a given direction; third and fourth link mechanism respectively connected to the second rod member and mounting thereon a rear part of the seat pan, the third and fourth link mechanism raising the rear part of the seat pan when the second rod member is rotated about its axis in a given direction; and first and second drive mechanisms mounted to the first base plate for turning the first and second rod members respectively. Each drive mechanism has a one-way clutch function which locks parts of the drive mechanism when a torque is applied thereto from the associated rod member. The first rod member has a sector gear connected thereto and operatively engaged with the first drive mechanism. The sector gear is positioned at an opposite side of the second drive mechanism with respect to the first drive mechanism.
