Abstract
The present invention discloses a latch for securing a seatback to an elevated rear wall of a vehicle passenger compartment, and in which a striker having a crosswise engaging portion extends rearwardly from the seatback. The latch includes a fixed sector adapted to being mounted to the rear wall. A hook is pivotally supported to the sector, with a slide plate sandwiching the hook between the slide plate and the fixed sector such that upward displacement of the slide plate causes forward pivoting of the hook. Rearward pressing of the seatback and striker causes rearward rotation of the hook to receive the striker, the slide plate being upwardly displaced to cause forward rotation of the hook to disengage the striker.
Claims17
A latch for securing a seatback to an elevated rear wall of a truck cab, a striker having a crosswise engaging portion and extending rearwardly from the seatback, said latch comprising:
- a fixed sector adapted to being mounted to the rear wall;
- the seatback adapted to being bolted to a floor so that the seatback extends at an angle relative to the rear wall, a minimal gap existing between an upper rear edge of the seatback and the truck cab wall;
- a hook pivotally supported to said sector, a slide plate sandwiching said hook between said slide plate and fixed sector such that upward displacement of said slide plate causes forward pivoting of said hook;
- said slide plate further having an uppermost curved and underside catch engaging portion with a top accessible curved underside profile;
- a coil spring with a first end engaging an upper location of said slide plate and a second end engaging a bottom shelf of the fixed sector, this in order to bias said slide plate in a downward direction to maintain said hook in a rear pivoted and engaging relationship with the striker;
- and
- rearward pressing of the seatback and striker causing rearward rotation of said hook to receive the striker, said slide plate being upwardly displaced to cause forward rotation of said hook to disengage the striker.
A latch assembly for securing a seatback to an elevated rear wall of a vehicle passenger compartment, a striker having a crosswise engaging portion and extending rearwardly from the seatback, said assembly comprising:
- a latch having a fixed sector adapted to being mounted to the rear wall;
- a hook pivotally supported to said sector;
- a slide plate sandwiching said hook between said slide plate and fixed sector, said slide plate having an underside catch engaging portion with a top accessible underside profile;
- a tool having a configured engaging tip which is adapted to being inserted through a gap between the seatback and wall, said tip engaging the slide plate such that upward displacement of said slide plate causes forward pivoting of said hook;
- and
- rearward pressing of the seatback and striker causing rearward rotation of said hook to receive the striker, said slide plate being upwardly displaced to cause forward rotation of said hook to disengage the striker.
A latch for securing a seatback to an elevated rear wall of a truck cab of a vehicle passenger compartment, the seatback adapted to being bolted to a floor so that the seatback extends at an angle relative to the rear wall, a minimal gap existing between an upper rear edge of the seatback and the truck cab wall, a striker having a crosswise engaging portion and extending rearwardly from the seatback, said latch comprising:
- a fixed sector adapted to being mounted to the rear wall;
- a hook pivotally supported to said sector, a slide plate sandwiching said hook between said slide plate and fixed sector such that upward displacement of said slide plate causes forward pivoting of said hook;
- an elongated slot defined in said slide plate, a pin shaft extending from said fixed sector through a mounting aperture in said hook and through said elongated slot so that an enlarged head of said pin shaft supports against said slide plate;
- said sector, hook and slide plate each further having a plate shape in a stacking arrangement;
- said slide plate being biased, via a coil spring extending between said slide plate and said fixed sector;
- and
- rearward pressing of the seatback and striker causing rearward rotation of said hook to receive the striker, said slide plate being upwardly displaced against a bias of said coil spring to cause forward rotation of said hook to disengage the striker.
