Abstract

A seat mounted on a slide slidable on a track. The track has comfort and entry zones. Pitch linkage mounts on the slide and supports a seat back. The linkage pivotally connects a seat back to the slide between recline and forward positions. A track latch fixes the slide to the track in a plurality of positions in the comfort zone. The entry zone is used to enter the vehicle. A forward stop blocks the slide from moving from the comfort to the entry zone. The forward stop moves between stop and release positions. The stop position blocks the slide from moving from the comfort to the entry zone. The release position does not block the slide from moving. A forward stop mechanism moves the forward stop into the stop position when the pitch linkage is in the recline position and the slide is in said comfort zone.

First claim

What is claimed is:

1. An adjustable seat mechanism for a seat with a seat cushion and a seat back, the seat mechanism comprising:
a track having a first longitudinal end, a second longitudinal end and an overall slidable length, said overall slidable length having a comfort range and an entry zone, said entry zone being arranged between said comfort zone and said first longitudinal end;
a slide movably mounted on said track to slide along said overall length, said the slide being adapted to support the seat cushion;
pitch linkage mounted on said slide and adapted to support the seat back, said pitch linkage pivotally to connect the seat back to the slide between a recline position and a forward position;
a track latch arranged on said slide and to fix said slide to said track in a plurality of track positions in said comfort zone;
a forward stop on said slide and selectively to block said slide from moving from said comfort zone to said entry zone, said forward stop being movable between a stop position and a release position, said stop position to block said slide from moving from said comfort zone to said entry zone, said release position not blocking said slide from moving from said comfort zone to said entry zone;
a forward stop mechanism to move said forward stop into said stop position when said pitch linkage is in said recline position and said slide is in said comfort zone.

2. A seat mechanism in accordance with claim 1 , wherein:
said forward stop mechanism biases said forward stop into said stop position when said pitch linkage is in said recline position.

3. A seat mechanism in accordance with claim 1 , wherein:
said track latch is movable between a latch position and an unlatch position, said latch position to fix said slide to said track in one of said plurality of track positions, said unlatch position not to fix said slide to said track in one of said plurality of track positions;
a latch mechanism moves said track latch into said unlatch position when said pitch linkage is in said forward position.

4. A seat mechanism in accordance with claim 3 , wherein:
said latch mechanism biases said track latch into said latch position when said pitch linkage is in said recline position.

5. A seat mechanism in accordance with claim 4 , wherein:
said track latch includes a tooth member to interact with a plurality of slots to fix said slide to said track in said plurality of track positions, said tooth member being arranged on one of said track and said slide, said plurality of slots being arranged on the other of said track and said slide;
said latch mechanism includes a cam surface between said track latch and said pitch linkage, movement of said pitch linkage to move said cam surface of said latch mechanism to move one of said tooth member and said plurality of slots.

6. A seat mechanism in accordance with claim 1 , wherein:
a pitch mechanism blocks movement of said pitch linkage from said forward position to said recline position when said slide is in said entry zone.

7. A seat mechanism in accordance with claim 1 , further comprising:
a rearward stop on said slide and selectively to block said slide from moving to said second longitudinal end, said rearward stop being movable between a stop position and a release position, said stop position of said rearward stop to block said slide from moving to said second longitudinal end, said release position of said rearward stop not to block said slide from moving to said second longitudinal end;
a rearward stop mechanism moving said rearward stop into a respective said stop position when said pitch linkage is in said forward position and said slide is in said comfort zone.

8. A seat mechanism in accordance with claim 7 , wherein:
said rearward stop mechanism moves said rearward stop into a respective said release position when said pitch linkage is in said recline position.

9. A seat mechanism in accordance with claim 7 , wherein:
said rearward stop includes a rearward hook and a rearward obstacle, said rearward hook and said rearward obstacle being arranged to have said rearward hook engage with said rearward obstacle in a respective said stop position;
said rearward stop mechanism includes a rearward rocker with said rearward hook being arranged on said rearward rocker, said rearward rocker with said hook being arranged on said slide;
said rearward rocker includes a rear cam surface between said rearward stop and said pitch linkage, said rear cam surface in said stop position of said rearward stop to block said pitch linkage from moving from said forward position to said recline position.

10. A seat mechanism in accordance with claim 1 , wherein:
said forward stop includes a hook and a forward obstacle, said hook and said forward obstacle being arranged to have said hook engage with said obstacle in a respective said stop position, said hook and said forward obstacle being arranged to not have said hook engage with said obstacle in a respective said release position, said forward obstacle being arranged on said track;
said forward stop mechanism includes a cam surface between said forward stop and said pitch linkage, movement of said pitch linkage to move said cam surface to move said hook;
said forward stop mechanism includes a rocker with said hook being arranged on said rocker, said rocker with said hook being arranged on said slide.

11. A seat mechanism in accordance with claim 1 , wherein:
said slide includes a side plate;
said pitch linkage, said forward stop, a rearward stop, and a pitch lock are pivotally mounted to said side plate;
a forward obstacle, a rearward obstacle and a pitch obstacle are mounted said adjacent a same transverse side of said track, in longitudinal alignment and under said slide.
