Abstract
ABSTRACT OF DISCLOSURE
A cinch strap is provided which is generally of two-part construction. The first part comprises a tensile load-carrying band and buckles are secured to opposite ends thereof so that the strap can be fastened to a saddle. The second part comprises a resiliently compressible, cushioning band secured in face to face relationship with the first part. A closed loop is formed at the centre of the strap by respective lengths of the bands and the respective length of the first band lies in a slack bight in an unstressed condition. When the strap is subjected to increasing longitudinal tensile load, for example, by the body of a horse the respective length of the second band stretches until the slack is taken up and any further increase in load is shared between both lengths.

STRAP
Field of Invention _ _ The present invention relates to a strap, for example in the equestrian equipment field a saddlery body strap such as a girth or cinch, for securing a saddle in position, which in use lies against the body oE the horse and which is subjected to a tensile load.
Background of Inve~tio_ n In their traditional construction such saddlery body straps have been made of leather, but other materials have also been used and, in particular, the use of carefully selected materials based on various synthetic plastics has found some favour in recent times. Also, it is known to incorporate padding or cushioning materials in the construction of such body straps in order to improve comfort and reduce the risk of chafing and injury to the body of the horse.
In producin~ such body straps, however, it is also frequently necessary to ensure that their overall resilient stretching characteristics or elasticity under tensile load falls within closely defined limits. This can be a general requirement, but control of this overall elasticity combined with a high breaking strength can be especially important when the strap is likely to be subjected to high and variable tensile loading, as for instance in the case of a cinch used

In producin~ such body straps, however, it is also frequently necessary to ensure that their overall resilient stretching characteristics or elasticity under tensile load falls within closely defined limits. This can be a general requirement, but control of this overall elasticity combined with a high breaking strength can be especially important when the strap is likely to be subjected to high and variable tensile loading, as for instance in the case of a cinch used
2 ~ 33~a for securing a "Western type" saddle on a horse which may take part in very energetic activities like rodeo ridiny.
By way of example, in my prior U.S. Patent No. ~132n55 there is disclosed a body strap of equestrian harness or saddlery equipment made up basically of a tubular webbing sheath which is formed of woven yarn composed of staple fibres of synthetic polymer material and which is filled with an insert of foam expanded plastics material to provide cushioning characteristics, end straps carrying strap fastening fittings such as buckles being secured to the ends of the sheath, and the overall elasticity is controlled by securing to the sheath discontinuol~s reinforcing band or strip portions having an elasticity or resilient stretch less than that of the sheath material.

relatively so~t resiliently compre~sible cushioning characteristics, said strap including at least one loop region formed by a loop section of preselected length o~ the first strap portion being secured at its opposite ends to the opposite ends of a loop section oE the second strap portion which has a preselected length less than that o~ said first strap portion loop section such that the latter lies in a slac~ bight sparned by said second strap portion loop section, whereby in use under an increasing tensile load initially said load is carried in the loop region, or in each such loop region, by the second strap portion loop section which stretches and extends longitudinally until the slack of the bight of the first strap portion loop section is taken up whereupon any further increase in the tensile load is then shared in said loop region or regions between the first and second strap portion loop sections so providing an abrupt increase in resistance to stretching. Preferably, the or each loop region provides, during initial longitudinal stretching of the strap, a longitudinal region of the strap having an elasticity equal to if not greater than any other longitudinal region of the strap.
In preferred embodiments the second strap portion has a greater elasticity, that is~ it has a smaller modulus of elasticity and will resiliently stretch further under a tensile load in a longitudinal direction, than the first strap portion. For saddlery hody straps, the second strap portion is in fact preferably in the form oE an elongate ~31~
tubular webbing sheath woven from yarn composed oE staple fibres of synthetic polymer material and having an insert filling of cushioning material composed of at least one strip of foam expanded plastics material as described in my above-mentioned previous Patent, while the first strap portion is preferably provided by one or more relatively high tensile strength continuous webbing bands or strips of woven nylon or like material secured directly at their ends to the end fastening fittings.
The relative lengths of the first and second strap portion loop sections of the or each loop region should in all cases be such that under load the slack of the bight of the first strap portion loop section is taken up before there is any risk of the corresponding second strap portion loop section stretching and extending beyond its elastic limit.
It will usually be preferred for a saddlery body strap in accordance with the invention to be provided with a single said loop region which will be located midway along its length, and the remainder of the band or strip, or each band or strip, making up the first strap portion outside the loop region will be secured along its length, as by stitching, to the second strap portion. The latter may advantageously extend beyond the ends of the first strap portion so that its end portions provide free end flaps adapted to overlie the buckles or other end fastening fittings and protect the body of the horse from contact with the latte`r during use.

Advantageously, the bight of the first strap portion loop section in the or each loop region may be partly confined in place by a transversely-extending layband loop secured to the second strap portion loop sectior.
Brief Description Of The Drawings Other advantageous features will be apparent from the following description, presented by way o~ example only of a preferred embodiment, relating to a cinch which is constructed in accordance with the invention as illustrated in the accompanying drawings.

Figure 2 is a similar rear elevational view thereof;
Figure 3 is a longitudinal section on line III-III of Figure 1 which has been inverted;
Figure 4 is a transverse sectional view on line IV-IV

Descri tion Of Preferred Embodiment P . _ . . .
Referring to the drawings, the cinch illustra-ted therein is a body strap of a kind commonly used for securing a l'Western type" saddle to a horse and~ in use/ it lies around the underside o~ the body of the horse and has its ends 33~
attached to straps clepending at each side from the saddle.
In this embodiment, as shown, the cinch 10 comprises a pair of parallel continuous bands or strips 12, 12, whlch constitute a first strap portion connectecl at opposite ends directly to buckle end fittings 14. These bands or strips 12, 12, are tensile load-carrying members and are advantageously composed of nylon braid or webbing having a high breaki~g strength.
Overlying these bands or strips 12, 12, at the back, in face to face relationship therewith, is another relatively wide flat band or strip, constituting a second strap portion, which is in the Eorm of a sheath member 15 of substantially rectangular cross-section made up of an elongate -tubular webbing sheath envelope 16 containing, as an insert filling, a strip 18 of foam cross-linked expanded polyethylene or similar foam expanded plastics material providing relatively soft resiliently compressible cushioning characteristics.
The sheath envelope 16 itself is advantageously formed of woven yarn composed of staple polyester fibre such as a "Terylene" fibre having a texture and appearance very similar to woven cotton f abric.
~ s shown, the sheath member 15 is secured to the bands or strips 12, 12, of the first strap portion by rectangular areas of machine stitching 20 which each extend continuously f rom th e bu ckl e end f i t t i n~J s l 4 a l onq the l eng th of th e ;~ 3~ i cinch up to a central loop region 22 where the sheath member and hands or strips 12, 12, are not secured together. This loop region 22 may be regarded as being formed by a section 12a, termed a loop section, of each band or strip 12, which loop section has a preselected length, being secured at its opposite ends tby the machine stitched areas 2~) to the opposite ends of a loop section 15a of the sheath member 15 which, in the unstressed condition, has a length less than that the loop section 12a such that the latter is folded into a bight spanned by the sheath member loop section 15a.
The bight loop sections 12a, 12a, of the bands or strips 12, 12, pass through a transverse layband loop 24 of webbing which is secured to the sheath member 15 midway along the length of the cinch as shown, this layband loop 24 also providing an anchorage for metal rings 26, 26, which may be used for attaching a breast strap to the cinch. The layband loop 24 serves partly to confine the bight loop sections 12a, 12a in place.
~0 It is a feature of this construction that the sheath member 15 has a substantially greater elasticity than the nylon bands or strips 12, 12, of the first strap portion such that it stretches and resiliently extends further than the latter when subjected to tensile load, that is, it has a smaller modulus of elasticity. As a result, under light loads the cinch has a relatively high elasticity and will extend by stretching o~ the central loop section 15a of the `~ 33~
sheath member which carries all the tensile load in this region. This enables the cinch to be designed so that under light loads it has sufficient "give" as not to restrict unduly movements of the horse's body and to ensure a comfortable fitting. Under increasing tensile load, however, a stage can be reached when the extension of the loop section 15a is such that all the slack of the bight loop sections 12a, 12a, is taken up and any further increase in load is shared, with the major part being borne by these loop sections 12a, 12a. This provides an abrupt increase in resistance to stretching and the cinch becomes relatively inextensible while the relatively high breaking strength of the bands or strips 12 r 12, which then form the principal load carrying members extending continuously between the two end buckle fittings 14, 14, gives a high degree of security under conditions in which the cinch is likely to be severely stressed.
`~ 33~
This form of construction provides a particularly convenient means for controlling the overall elasticity characteristics, and apart from selecting the materials of appropriate physical characteristics, the extent of the loop region and relative lengths of the loop sections can be varied as required. Also, a plurality oE similar loop regions may be provided spaced a]ong the length of the strap, although a sinqle loop region in the middle, as specifically described, may be preferred from the point of view of reducing the number of separate stitching operations necessary.
In the embodiment illustrated, it should also be noted that the sheath member 15 extends beyond the ends of the bands or strips 12, 12, so as to provide free end flaps 30, 30, which can overlie the buckles 14, 1~, at the rear and serve to prevent the latter from contacting the body of the horse during use.
It will be appreciated that various modifications in the construction herein specifically described by way of example may be made, ii desired, within the scope oi the invention.

The relative lengths of the first and second strap portion loop sections of the or each loop region should in all cases be such that under load the slack of the bight of the first strap portion loop section is taken up before there is any risk of the corresponding second strap portion loop section stretching and extending beyond its elastic limit.
It will usually be preferred for a saddlery body strap in accordance with the invention to be provided with a single said loop region which will be located midway along its length, and the remainder of the band or strip, or each band or strip, making up the first strap portion outside the loop region will be secured along its length, as by stitching, to the second strap portion. The latter may advantageously extend beyond the ends of the first strap portion so that its end portions provide free end flaps adapted to overlie the buckles or other end fastening fittings and protect the body of the horse from contact with the latte`r during use.
