Shoulder adjuster

The shoulder adjuster as set forth in claim 8, wherein said anchor fitting part is intruded resisting the biasing force of said elastic member when pushing said anchor fitting part in a direction vertical to said guide rail, said engaging parts separate from said notches, and said slide member becomes movable in a downward direction of said guide rail.

A shoulder adjuster for a vehicle comprising:

• an elongated guide rail fixed to the vehicle to extend in a vertical direction and having a plurality of notches at intervals in a longitudinal direction, each notch having a lower cut-in edge part orthogonal to the longitudinal direction of the guide rail and an upper cut-in edge part obliquely to the longitudinal direction of the guide rail to expand an aperture of the notch,
• a slide member attached to the guide rail to slide along the longitudinal direction thereof and having engaging parts engaging the notches of the guide rail, and
• an anchor fitting part having a lower side attached to the slide member, an upper side adapted to attach to a shoulder anchor for a seat belt, and an elastic member situated between the guide rail and the anchor fitting part for urging the anchor fitting part in a direction away from the guide rail to thereby bias the engaging parts of the slide member to the notches of the guide rail so that when the upper side of the anchor fitting part is pushed against a biasing force of the elastic member, the engaging parts of the slide member disengage from the notches of the guide rail to allow the anchor fitting part to move freely.
