Abstract

Safety harness comprising a waistband to be wrapped around a person, shoulder suspenders projecting from the top of the waistband and means for coupling the waistband to a supportive body, such as an automobile; the coupling means comprises two separate belts joining opposite sides of the waistband to the supportive body; an openable coupling in each belt, which coupling includes a swivelable lock handle, which is adapted to be swiveled substantially simultaneously with the grasping and removal of the person from the supportive body; in additional embodiments, means connect the swivelable handles for both belt couplings so that swivel of one handle also swivels the other and releases the waistband.

Claims

1. A safety harness arrangement for restraining a person, comprising:

a waistband to be secured to the person to be restrained;

said waistband having a forward portion in front of the person and having sides at the sides of said forward portion;

at least one belt connected to one said waistband sides for joining said waistband to a support, said belt has a top edge and a bottom edge when said belt is attached to said waistband;

coupling means in said belt, said coupling means being separable to separate said waistband from said belt;

said coupling means comprising a first coupling element connected to said waistband and a second coupling element connected to the separable part of said belt;

one of said first and second coupling elements comprising a latching means and the other of said first and second coupling elements comprising a latch element that is to be latched onto by said latching means and that is to be released from latching by said latching means;

said latching means including a mechanism for engaging said latch element;

a handle connected to said latching means mechanism;

said handle being swivelingly connected to a swivel on the one of said belt and said waistband to which said handle is connected;

said latching means mechanism, said latch element and said handle being so shaped and located that upon swiveling of said handle in the direction toward said waistband, said latching means is uncoupled from said latch element, said handle and its said swivel being oriented and adapted to enable said handle to swivel in a plane generally parallel to the plane joining said belt top and bottom edges at the position of said swivel along said belt;

said handle projecting beyond one of said edges of said belt, such that contact with said handle beyond that said one edge of said belt by motion in the direction toward said waistband swivels said handle to open said latching means.

2. The safety harness arrangement of claim 1, wherein said handle projects below said belt bottom edge.

3. The safety harness arrangement of claim 2, wherein said latch element comprises a post and said latching means mechanism is adapted to engage said post in a manner that precludes separation of said belt from said waistband, and is adapted to be uncoupled from said post by swiveling of said handle.

4. The safety harness arrangement of claim 3, wherein said post is said first coupling element and said latching means is said second coupling element.

5. The safety harness arrangement of claim 1, wherein there are at least two said belts, one said belt being fastened to one of said sides of said waistband and the other said belt being fastened to the other of said sides of said waistband;

a respective said coupling means in each said belt.

6. The safety harness of claim 5, further comprising means linking said handles of said coupling means to shift together such that swiveling movement of one said handle toward said waistband causes simultaneous swiveling movement of the other said handle toward said waistband.

7. The safety harness of claim 6, wherein said linking means comprises a tie connected to and extending between the side of one said handle above its respective said swivel with the side of the other said handle below its respective said swivel, such that swiveling of one said handle through said tie swivels the other said handle.

8. The safety harness of claim 6, wherein said linking means comprises a tie connected to and extending between the same side of each said handle with respect to their respective said swivels, such that pulling said tie swivels both said handles toward said waistband.

9. The safety harness of claim 5, wherein said waistband is of sufficient length to wrap about the person wearing it and is adjustable in length.

10. The safety harness of claim 9, wherein said waistband has substantially greater height along the body of the wearer than said belts thereby to provide a supporting vest for the wearer.

11. The safety harness of claim 9, wherein said waistband forward portion is positioned in front of the person wearing it and is between said belts;

said waistband forward portion and said belts with their said coupling means comprises a single normally unitary separable unit.

12. The safety harness of claim 9, wherein said waistband is defined by a length of material having end portions which are brought together when said waistband is wrapped about a wearer;

at said end portions are fastening means for holding said waistband closed around the wearer.

13. The safety harness of claim 12, wherein said waistband fastening means are adjustable to permit adjustment of the length of said waistband.

14. The safety harness of claim 13, wherein said fastening means comprise a slipless flat locking mechanism comprised of panels with joinable surfaces, with one said surface on each said end portion.

15. The safety harness arrangement of claim 1, wherein said latching means mechanism comprises a latching element engaging tab;

said handle having a lip facing away from said waistband for engaging said latching element and said lip and said tab being so positioned that said latching element is held between them;

said handle lip being so placed with respect to said swivel that upon swiveling of said handle toward said waistband said lip moves away from and thereby releases said latching element.
