Abstract
A seat belt holder position adjuster is disclosed which adjusts the height of a belt holder which supports an uppermost portion of a shoulder belt part of the seat belt. The adjuster comprises an elongate base unit formed with a plurality of latch holes, an anchor unit disposed on the base member in a manner to slide therealong, a belt holding member connected to the anchor unit to move therewith, and a latch pawl unit mounted on the anchor unit. The latch pawl unit includes two shank portions which are latchingly engageable with selected pair of the latch holes of the base member and at least one spring for biasing the shank portions in a direction to establish a latching engagement between the shank portions and the selected pair of the latch holes.
Claims61
A seat belt holder position adjuster comprising:
- a base unit including an elongate base member having two adjacent rows of latch holes formed therethrough;
- an anchor unit disposed on said base unit in a manner to slide therealong;
- a belt holding member connected to said anchor unit to move therewith;
- and
- a latch pawl unit mounted on said anchor unit, said latch pawl unit including a generally U-shaped monolithic latch piece having two shank portions which are sized and arranged to be latchingly engageable with an adjacent pair of latch holes, said pair comprising a latch hole from each of said two adjacent rows of the base unit, and a biasing means for biasing said latch piece in a direction to achieve latching between said shank portions and said paired latch holes,
- wherein said anchor unit includes guide holes through which said shank portions of said latch pawl unit are passed to be exposed to said elongate base member, an anchor member, and a guide member tightly held by said anchor member, said guide member having at its sides mutually facing guide grooves by which said base member is slidably guided.

A seat belt holder position adjuster comprising:
- an elongate base member formed with a plurality of latch holes which are arranged in two rows;
- a guide member having at its both sides mutually facing guide gooves by which said base member is slidably held;
- an anchor member tightly holding therein said guide member to constitute an anchor unit, said anchor unit being formed with two guide holes formed therethrough;
- a shaft fixed to said anchor unit;
- a cylindrical latch guide member disposed on said anchor unit in a manner to surround said shaft;
