Patent ID: 8517425

Claim:
An anchor pretensioner structure for cars, comprising: an inflator mounted on a car-body plate to pull a seat belt upon a collision; a pretensioner wire made of a flexible material and connected to the inflator; a protector mounted to the pretensioner wire coupled to the seat belt; and an angle-adjuster having: a linear drive body mounted on the car-body plate; and an operating rod slidably mounted in one side of the linear drive body, wherein the pretensioner wire is engaged to the operating rod and wherein the operating rod moves in association with the pretensioner wire in linearly reciprocating through the linear drive body while the inflator actuates the operating rod, and wherein the inflator is adapted to linearly move the operating rod depending upon whether or not a passenger is sitting on a seat, so that the pretensioner wire is allowed to rotate by a predetermined angle when the operating rod linearly moves by actuation of the inflator.
