Abstract
A vehicle seat system includes a seat including a seat back and a seat base and a passive restraint system mounted adjacent to the seat. The passive restraint system includes a lap belt. A belt adjuster is mounted at the seat. The belt adjuster includes a member operable to engage and shift the lap belt away from the seat back upon being exposed to a selected deceleration force.
Claims16
A vehicle seat system for a vehicle comprising:
- a seat including a seat back and a seat base;
- a passive restraint system mounted adjacent to the seat, the passive restraint system including a lap belt including an anchor fixedly mounted to the vehicle;
- and
- a belt adjuster mounted at the seat, the belt adjuster including a member operable to engage the lap belt at a position spaced from the anchor and shift the lap belt away from the seat back upon being exposed to a selected deceleration force, the belt adjuster including a housing mounted to the seat base, the housing including an outer surface and a guide track defined in the outer surface, the member being constrained to selectively move along the guide track.

A vehicle comprising:
- a body defining a passenger compartment;
- and
- a vehicle seat system arranged in the passenger compartment, the vehicle seat system comprising:
- a seat including a seat back and a seat base;
- a passive restraint system mounted adjacent to the seat, the passive restraint system including a lap belt including a fixed anchor mounted in the passenger compartment;
- and
- a belt adjuster mounted at the seat, the belt adjuster including a member operable to engage the lap belt at a position spaced from the anchor and shift the lap belt away from the seat back upon being exposed to a selected deceleration force, the belt adjuster including a housing mounted to the seat base, the housing including an outer surface and a guide track defined in the outer surface, the member being constrained to selectively move along the guide track.

A vehicle seat system for a vehicle comprising:
- a seat including a seat back and a seat base;
- a passive restraint system mounted adjacent to the seat, the passive restraint system including a lap belt including a fixed anchor;
- a belt adjuster mounted at the seat, the belt adjuster including a member operable to engage the lap belt at a position spaced from the fixed anchor and shift the lap belt away from the seat back upon being exposed to a selected deceleration force, the belt adjuster including a housing mounted to the seat base, the housing including an outer surface and a guide track defined in the outer surface, the member being constrained to selectively move along the guide track;
- an activation mechanism operatively connected to the member;
- and
- a control system operatively connected to the activation mechanism, the control system including a central processing unit (CPU), an activation module, and a non-volatile memory having stored thereon a set of instructions, which when executed by the CPU, causes the CPU to instruct the activation module to trigger the activation mechanism to release the member to move the lap belt in response to a sensed deceleration event having the selected deceleration force.
