AI Technical Summary

Benefits of technology

The low-profile clamp has several advantages. It can be used as a cutting edge to remove excessive band length, resulting in sharp edges and avoidance of tolerances. The locking remains visible and is protected from external influences. The side edges of the band can be chamfered or cut out to avoid interference on the tool. The inner band end portion can be tapered or bevelled to minimize friction and improve fixation. The clamp may also have inner projections to engage the band's side edges for better fixation.

Problems solved by technology

All these low-profile clamps involve the problem that the force which is applied to the punch for locking the band ends within the buckle acts on the object to be fastened and may damage the same.

Embodiment Construction

[0029]The low-profile clamp shown in FIG. 1 of the drawings includes a band 20 and a buckle 21. Both parts are preferably made of metal. The figure shows a condition in which the low-profile clamp is fixed to an inner band end portion 22, the band 20 surrounds an object to be fastened (not shown), and the outer band end portion 23 is fed through the buckle 21. In the final mounting, the band 20 is tightened around the object to be fastened by tension applied to the outer band end portion 23, the outer band end portion 23 is locked in the tightened condition by being deformed within the buckle 21, and the excessive length of band is cut off closely behind the buckle 21.

[0030]To improve the handling in feeding the band 20 through the buckle and to reduce the risk of injury, the end 24 of the outer band end portion 23 may be rounded ore chamfered (see FIG. 14).

[0031]FIGS. 2a to 2d show formations of the inner band end portion 22 that are suitable for fixing within the buckle 21. In acc...

Abstract

A low-profile clamp consists of a band (20) and a buckle (21) mounted on a first end portion of the band. During mounting, the second and portion (23) of the band (20) which surrounds the object to be fastened is fed through the buckle (21); after tightening the band is locked to the buckle (21) by deformation. The deformation may be done with a plier-type tool which engages the side edges (37) of the second band end portion (23) through lateral windows (36) formed in the buckle (21).

Description

PRIOR ART[0001]For fastening an object such as an air bag material on a gas generator or an air bag on a mounting plate, low-profile clamps are used which consist of a band and a buckle disposed on one end portion of the band. During installation, the other end portion is wound around the object to be fastened and fed through the buckle. For tightening, the other band end is tensioned, and the band and the buckle are locked together in the tightened condition whereupon the excessive length of the outer band end is cut off.[0002]In a low-profile clamp of this type, as known from U.S. Pat. No. 8,424,166 B2, the buckle, which surrounds both end portions of the band, has a hole in the outer side remote from the object to be fastened for receiving a punch by which the band end portions are deformed and thereby locked together.[0003]Similar low-profile clamps are known from U.S. Pat. No. 3,754,303, U.S. Pat. No. 7,373,695 B2 and U.S. Pat. No. 7,650,680 B2, in which the buckle is initially...
