Abstract
An improved seat belt for a child car booster seat, having a novel five-point seat belt harness with a belt adjusting mechanism. A novel belt tightening and loosening mechanism is disclosed. The booster seat may be secured preferably by one of two ways: either employing belts that secure the booster seat from the rear, or employing a traditional automobile shoulder and lap belt harness to secure both the user and the booster seat. When using an automobile shoulder and lap belt harness mode of securing the booster seat, a shoulder belt clasp is employed to keep the shoulder belt away from the child user's face and neck.

A vehicle booster seat belt system comprising:
- a booster seat;
- a five point seat belt harness on said seat, said five-point harness having two shield halves, a right hand side shield half and a left hand side shield half, each of said shield halves having a tongue and each said shield half connected to a belt, and a crotch buckle receiving both of said tongues from said two shield halves;
- said belts for said shield halves including a generally longitudinally extending shoulder belt and a generally laterally extending lap belt, said longitudinally extending shoulder belt attached to said booster seat at the back of said booster seat, and a tightening and securing mechanism for tightening said belts, said mechanism comprising a stamping plate lying substantially in a single plane and attached to said seat back of said booster seat, and a lever pivotally attached to said stamping plate for motion in a plane substantially parallel to the plane of said stamping plate wherein one of said longitudinally extending shoulder belts wrap around said lever wherein pulling on said belts tightens the seat belts, and moving said lever loosens said seat belts.
A five-point seat belt system for a seat comprising:
- a seat having a seat base and a seat back;
- a fastening device comprising a pair of shield halves having tongues received by a buckle;
- said pair of shield halves each attached to a belt, said belt having a generally vertically extending longitudinal belt portion and a generally laterally extending lateral belt portion,said pair of shield halves have a portion enlarged in a generally oval shape and having a plurality of slots therein to allow a belt to pass through said slots, said oval shaped shield halves being sufficiently large to act as supplemental restraints for the pelvis of a child using said booster seat;
- said lateral belt and longitudinal belt portions of said belt associated with each of said shield halves being a single belt, said single belt passing through said slots in said shield halves, and an end of said single belt detachably secured to the back of said seat back;
- said buckle fixed to a web that is attached to said seat base;
- and
- a tightening and securing mechanism for tightening said single belts, said mechanism comprising a stamping plate lying substantially in a single plane and attached to said seat back of said booster seat, and a lever pivotally attached to said stamping plate for motion in a plane substantially parallel to the plane of said stamping plate wherein said one of said single belts wraps around said lever, wherein pulling on said belt end tightens the single seat belt, and moving said lever loosens said single seat belt.
