Abstract
Abstract Disclosed herein is a seat which is mounted on a vehicle frame for pivotal movement relative to an in-use position, together with a parking brake operable to prevent vehicle movement upon movement of the seat through a first predetermined distance from the in-use position, and a latch mechanism on the seat and on the frame and including first means for preventing movement of the seat through the first predetermined distance from the in-use position, and second means selectively movable between first and second positions, and being operable, when in the first position, for preventing limitation of movement of the seat by the first means, whereby to allow pivotal movement of the seat from the inuse position beyond the first predetermined distance, and for preventing movement of the seat through a second predetermined distance greater than the first predetermined distance from the in-use position and, when in said second position, for permitting seat movement prevention by the first means and for effecting movement of the second means to the first position upon movement of the seat toward the in-use position from a position at the first predetermined distance from the in-use position.

Claim 5
Dependent Claim
41 words
A seat latch mechanism in accordance with claim 2 wherein said second means is movable to a second position spaced from said first position and being operable, when in said second position, for permitting seat movement prevention by said first means.
Claim 6
Dependent Claim
53 words
A seat latch mechanism in accordance with claim 2 wherein said second means is movable to a second position spaced from said first position and being operable, when in said second position, for effEcting movement of said second means to said first position upon movement of said seat toward said first seat position.
Claim 7
Dependent Claim
19 words
A seat latch in accordance with claim 3 including means biasing said seat away from said first seat position.
Claim 8
Dependent Claim
