A door checker which can be advantageously utilized for driving automotive equipment such as a seat belt reacher system in synchronization with the opening and closing action of the vehicle door. By appropriate arrangement of a spring and a taper in the door checker member, the force required to open and close the door is not unduly increased. By proper arrangement of the spring, the side thrust from the door checker member is always directed in one direction, whereby the structure for supporting the side thrust is simplified.

Door checker for seat belt reacher system

A seat belt tightening device for removing slack in a seat belt when the seat belt is required to positively restrain a passenger, comprising clamp members for clamping a part of the seat belt paid out from a retractor device; a winding member for winding thereonto a portion of the seat belt that is located ahead of the part clamped by the clamp means by a rotary motion; and a drive source for causing a rotational motion of the winding member. The winding member may be either integral with one of the clamp members or separate from both of them. Since the slack of the seat belt is removed simultaneously as the seat belt is clamped, the passenger is effectively restrained in case of a vehicle collision without being thrown forward due to any slack in the seat belt, and since the seat belt is allowed to pass through the tightening device without being obstructed under normal conditions the comfort of the passenger is assured by the action of the retractor which is typically provided in conjunction with the seat belt tightening device.

Disclosed is a seat belt forwarding system having a rotary arm carrying an end of a seat belt at its free end. The rotary arm is driven by a tension cable by way of a rotary unit having three transmitting members which are coaxially arranged and supported in a freely rotatable manner. By advantageous arrangement of the transmitting members, even when motion of the rotary arm is obstructed, spring means advantageously absorb the resultant force and no excessive force will be produced in the rotary unit. The first spring means biases the second transmitting member in a rearward direction while the second spring means is engaged between the second and the third transmitting members. The transmitting of force between the transmitting members is achieved by projections provided in the opposing surfaces of the transmitting members, in addition to the transmission of force between the second and the third transmitting members by the second spring means.
