An automobile child safety restraint system, comprising an anchoring bar at least one wire anchoring loop affixed to the tubular anchoring bar without welding, and a method of manufacturing same.

Description

' ' CA 02372829 2002-02-19 WELDLESS CHILD SAFETY RESTRAINT SYSTEM
FOR AN AUTOMOBILE
FIELD OF THE INVENTION
This invention relates to safety systems. In particular, this invention relates to a child seat safety restraint system for an automobile.
BACKGROUND OF THE INVENTION
The National Highway Traffic Safety Administration, Department of Transportation maintains rigid safety standards for motor vehicles. Title 49, Chapter V, Section 571.213, specifies requirements for child restraint systems used in motor 1 o vehicles, which is incorporated herein by reference.
In a typical child restraint system for an automobile, a specially built child safety seat is tethered to an anchoring structure built into the vehicle. Many existing automobile child restraint systems are deficient, and the anchoring structure can fail to adequately secure child seat in an accident. In a conventional child restraint system a loop of wire is welded to an anchoring bar which is in turn bolted to the vehicle chassis.
Welding can result in inconsistent joints and deteriorated surfaces surrounding the weld, which can weaken the anchoring structure. Welding is a slow, labour-intensive, and dirty process which creates quality control concerns, even when 2o welding is effected by a skilled welder. The effectiveness of a weld is typically assessed visually, and problems such as burn-through, metal fatigue in the material surrounding the weld, incomplete adhesion due to contaminants on the tubular components and so on, are not always avoidable. In automobile applications, these types of problems can cause serious safety concerns.
SUMMARY OF THE INVENTION
The present invention provides a weldless child restraint system wherein at least one wire anchoring loop is securely affixed to an anchoring bar without welding.
The invention thus provides a consistently strong and easy to assemble child restraint system which meets and exceeds relevant current requirements.

DETAILED DESCRIPTION OF THE INVENTION
The invention, illustrated in Figure 1, is a child safety restraint system for an automobile: An anchoring structure comprises an elongated, preferably tubular member or bar 10 affixed (bolted or by any other suitable means) to brackets 12, which in turn provide holes for bolting the anchoring bar 10 to the floor or chassis of an automobile. The anchoring bar 10 supports seat mounting brackets 14 to which the automobile seats (not shown) are mounted. The anchoring bar 10 as described thus far is conventional and will be well known to those in the automobile industry.
According to the preferred embodiment of the invention, wire anchoring loops 20 are affixed to the anchoring bar 10 without welding. In a first embodiment of the invention, illustrated in Figures 2A to 2C, the wire anchoring loop 20 has free ends 30 extending through the bar 10. The free ends 30 are swaged as at 32, the swages being preferably seated in recesses 34 formed in the top surface 1 OA
of the anchoring bar 10. Nuts 36 are affixed to the free ends 30, for example nuts 36 may be threaded and the free ends 30 of wire loop 20 provided with a compatible thread, or other suitable engaging means may be employed to affix nuts 36 to the free ends 30.
Preferably the nuts 36 seat in recesses 38 formed in the bottom surface l OB
of the anchoring bar 10 so that no portion of the wire anchoring loop 20 projects beyond the bottom surface l OB, as can be seen in Figure 2C. Preferably the tip of each free end 30 is then punched or flattened, to lock the nuts 36 securely in place. The anchoring bar 10 is thus locked between the swages 32 and the nuts 36. In this embodiment the free ends 30 extend through the anchoring bar 10 substantially centrally along the top and bottom surfaces 10A, l OB, respectively, so that the free ends 30 are oriented generally vertically; the wire anchoring loop 20 is bent forwardly so as to protrude from between the automobile seat bottom and seat back, to be exposed for use.
If desired a bushing, sleeve or other support 39 may be disposed over each free end 30 to provide support between the top and bottom surfaces 1 OA, 1 OB of the anchoring bar 10, as shown in Figure 2C.
In a further embodiment of the invention, illustrated in Figures 3A to 3C, 3o the free ends 40 of wire anchoring loop 20 extend through a cord of the curved front edge l OC of the anchoring bar 10, at an angle relative to the top surface 10A
of the anchoring bar 10. The anchoring loop 20 is thus positioned to protrude from between the automobile seat bottom and seat back, to be exposed for use. The free ends 40 are swaged as at 42, and the swage is preferably seated in recesses 44 formed in the curved front edge l OC. The tip 46 of each free end 40 is punched, flattened or otherwise deformed to form a head 46, thereby locking the anchoring bar 10 between the heads 46 and the swages 42. Preferably the heads 46 are seated in ovate recesses 48 formed in the bottom surface l OB of the anchoring bar 10, so that no part of the wire anchoring loop projects below the bottom surface lOB of the anchoring bar 10.
In a still further embodiment of the invention, illustrated in Figures 4A to Io 4C, the free ends 50 of wire anchoring loop 20 extend along a cord through the curved front edge l OC of the anchoring bar, as in the previous embodiment. In this embodiment, the free ends 50 are initially positioned to project beyond the bottom surface l OB of the anchoring bar 10, and the free ends 50 are then struck, preferably by a ball or other similar striking tool, to simultaneously form a recess 58 in the 15 bottom surface l OB of the anchoring bar 10 and a curve 56 in the free end 50 of the wire anchoring loop 20. This embodiment does not require swages in the wire anchoring loop 20, since the curved portions 56 of the free ends 50 are sunk into the recesses 58 formed in the bottom surface lOB and thereby set in the wall of the anchoring bar 10, as shown in Figure 4C, so the wire anchoring loop cannot slip 2o downwardly into the anchoring bar 10.
In a still further embodiment of the invention, illustrated in Figures SA to 5C, the anchoring bar 60 is roll formed. In this embodiment wire anchoring loops 20 are secured only to the top surface 60A of the anchoring bar 60, and are secured before the anchoring bar 60 is rolled into tubular form. The wire anchoring loop 20 is 25 swaged as at 62, to restrain the loop 20 against slipping down into the anchoring bar 10, and is secured beneath the top surface 60A as by nuts 64, as shown in Figure 5C, or in any other suitable fashion. In this embodiment the wire anchoring loop 20 is affixed to the portion of the metal flat which will become the front edge 60C, preset to the protrusion angle which will optimise exposure through the automobile seats for 30 use. The flat is then rolled to form the anchoring bar 60, preferably with the seam 61 located centrally along the bottom surface 60B, as shown in Figure SB. The front edge 60C may have a flattened portion, as best seen in Figure SC, so that the swages 62 and nuts 64 conform to the abutting surfaces of front edge 60C, to better stabilize the wire anchoring loop 20.
In a still further embodiment of the invention, illustrated in Figures 6A to 6B, the anchoring bar 70 is formed from mating extrusions 72, 74, which may for example be formed from aluminium. Free ends 82 of wire anchoring loop 20 are disposed through openings 76 in top extrusion 74 and the tips of free ends 82 are each secured with a head 86, formed by a nut, deformation or other suitable enlargement affixed to or formed in the tips of free ends 82. The bottom extrusion 72 is secured to 1o the top extrusion 74 by mating tongue 73 with channel 78. The head 86 is contained within a recess 78A in the floor of channel 78, so that when the extrusions 72, 74 are joined, the heads 86 on free ends 82 are supported by the tongue 73, which thus both stabilizes the wire anchoring loop 20 and prevents it from slipping into the anchoring bar 70.
Various embodiments of the present invention having been thus described in detail by way of example, it will be apparent to those skilled in the art that variations and modifications may be made without departing from the invention.
The invention includes all such variations and modifications as fall within the scope of the appended claims.
