Abstract

A device for introducing slack into and removing slack from a lap belt device while the device remains in its buckled configuration. The device has an inverted "T" configuration that includes a longitudinally extending first part that slidingly supports a shoulder harness and a transversely extending second part having return bends formed in its opposite ends that slidingly receives opposite ends of the shoulder harness to maintain the shoulder harness centered with respect to the first part. In a first embodiment, serrated teeth are formed in a lower end of the first part to grasp the harness and to prevent its sliding movement with respect to the first part of the device when the device is rotated from its unlocked position to its locked position. In a second embodiment, opposite ends of a rigid wire that is bent to form the device are transversely spaced apart from one another and perform the same harness-gripping function as the serrated teeth. Slack is introduced into the lap belt when the device slidingly engages the harness and slack is removed when the device is rotated into its locked position where the serrations or wire ends grasp the harness and prevent it from sliding. A simple reverse rotation unlocks the device and enables freedom of movement of the lap belt wearer.

Claims

1. A device that slideably engages a seat belt shoulder harness when unlocked to enable the introduction of slack into said harness without unbuckling the harness and that grasps said seat belt shoulder harness when locked to remove said slack, comprising:

a base member having a longitudinally extending part and a transversely extending part;

a return bend formed in each end of said transversely extending part;

a belt-gripping means formed in a first end of said longitudinally extending part;

said longitudinally extending part adapted to underlie and slidingly support said seat belt shoulder harness;

each return bend adapted to slidingly receive opposite longitudinally extending edges of said seat belt shoulder harness and to maintain said harness in centered relation relative to said longitudinally extending part;

said base member having a first, unlocked configuration where it forms an acute angle with a downwardly extending section of said seat belt shoulder harness;

said base member having a second, locked configuration where it forms an obtuse angle with said downwardly extending section of said seat belt shoulder harness;

said belt-gripping means preventing sliding movement of said seat belt shoulder harness with respect to said base member when said base member is in said locked configuration.

2. The device of claim 1, wherein said base member is formed of a flat, rigid material including a longitudinally extending first part and a transversely extending second part, and wherein said return bends are formed in opposite ends of said transversely extending part.

3. The device of claim 2, wherein said belt-gripping means is a serrated edge formed in a first end of said longitudinally extending first part.

4. The device of claim 1, wherein said base member is formed of a rigid wire that is bent to form a longitudinally extending first section and wherein a second section, transversely disposed to said first section, is formed by a pair of transversely extending return bends.

5. The device of claim 4, wherein said belt-gripping means is formed by opposite ends of said rigid wire, said opposite ends being longitudinally disposed and being transversely spaced apart with respect to one another.
