1. A vehicle shoulder adjuster comprising:

  • a guide rail shaped into a long plate and having a longitudinally extending slot at its central portion and a plurality of holes at both sides of the slot;

    a slider arranged along a vehicular compartment side of said guide rail and made slidable in a longitudinal direction of said guide rail, said slider having;

    a plate portion facing a front face of said guide rail at said vehicular compartment side,a cylindrical portion extending rearwardly from the plate portion to be fitted in said slot,a female thread formed in an inner circumference of said cylindrical portion of said slider for mounting a shoulder anchor, andholding portions formed at opposite sides of said plate portion extending around opposite sides of said guide rail permitting sliding motion along said sides; and

    retaining means for retaining said slider on said guide rail at a predetermined interval, said retaining means including;

    a lock plate arranged at a back side of said guide rail opposite to said vehicular compartment side and supported by said slider at one longitudinal side of said lock plate such that its longitudinal other side is made movable toward and apart from said slider;

    hooks formed at said lock plate and adapted to engage said holes to block sliding movement of said slider when said other side of said lock plate is brought to said slider; and

    a leaf spring supported by said slider and connected to said longitudinal other side of said lock plate for urging said longitudinal other side toward said slider so that when the leaf spring is pushed toward the guide rail, the lock plate inclines backward to disengage the hooks from the holes of the guide rail to allow the slider to smoothly slide along the guide rail without tilting against the guide rail.
