Clamp for retractor belt with actuator

A clamp (30) for relieving the tension in a seatbelt (22). An actuator is activated by the passenger at a location remote from the clamp to lock the clamp to the seatbelt. The clamp is slidable on a track with a first endstop (36) and an opposite second endstop (38). The clamp can be initially secured to the seatbelt at the first endstop (36). Subsequent movement by the passenger results in the clamp moving along the track. Upon reseating by the passenger, the clamp will be supported at a support position (42) intermediate of the first and second endstops, resulting in increased slack in the shoulder portion of the seatbelt, reduced tension in the shoulder portion, and increased comfort for the passenger.
