Description
~4~Z
This invention relates to a safety harness, particularly a safety harness for use by a sailor of a sailboat or sailboard.
The term "sailboard" as used in this application, refers to a sailing craft such as that described by Canadian Letters Patent 912,921 which issued October 24, 1972 to Hoyle Schweitzer and James Drake. A sailboard consists essentially of a flotation board, like a surfboard, having a free sail system, that is, a sail mounted on a universal joint or the like so as to be free to :Eall in any direction about the pivot point on the flotation board. During operation the sail is held upright by the sailor and manipulated and tilted to effect steering and control of the craft. Further the sailor is constantly pulling the sail against the force of the wind by holding on to the boom and leaning into the wind.
It is an object of this invention to provide a safety harness which may be worn by a sailor of a sailboard which is adapted to releasably connect to the boom of a sailboard to enable a sailor to lean back in the harness to counter the force of the wind in the sail.
There are other prior art harnesses available but many of these suffer the deficiency that because of their construction the forces in the harness tend to create local-i7ed pressures which are uncomfortable for the wearer. In the event of shock loading, as might occur during a fall, these localized pressures may increase to levels that may cause injury to the wearer.
It is an object of this invention to provide a safety harness of a novel construction which facilitates t~
~3~4~
distribution of forces to reduce localized pressure points and discomfiture to the wearer.
It is a further object of this invention to provide a safety harness having integral flotation foam which is united within the safety harness in a manner which enables it to assist in the transmission of forces and to cushion the effect of the squeezing pressures on the wearer. This flotation foam doubly serves to support the user in the water in the event of a fall.
The safety harness of this invention which is adapted to be worn by a sailor to secure himself to a sailboard or the like comprises essentially a vest jacket having padding as integral parts thereof a back, including left and right shoulder pieces adapted to ~it over the shoulders of a wearer, left and right underarm sides and left and right chest pieces adapted to be adjustably connected to the corresponding shoulder pieces; a securing means adapted to be releasably a-ttached to the sailboat or the like and to be attached to the left and right sides and shoulder pieces by first, second, third and fourth straps respectively so as to allow the force developed in the straps by the securing means to be distribu-ted over the sides and the back of the jacket thereby substantially reducing locali~ed pressure points and discomfiture to the wearer.
The safety harness vest jacket may comprise a composite sandwich of outer nylon fabric, at least a first layer of flotation foam and an inner nylon fabric. In accordance with the novel construction of this invention the straps leading from the securement means to the vest jacket are secured to the vest jacket at the sides and z shoulders in a manner which bonds the straps to both the outer nylon fabric and at least the first layer of flotation foam. This enables the forces developed in the straps to be transmitted to the outer nylon fabric and the first layer of flotation foam and to be distributed over the back shoulders and sides of the jacket. The flotation foam additionally cushions the effec~ of the forces as they are applied to the wearer of the jacket.
This is accomplished by having first and second straps attached to the sides of the jacket by means of stitching that penetrates and bonds together the outer nylon fabric and at least a first layer of flotation foam. Similarly, the third and fourth straps are a-ttached to the shoulder pieces by stitching that penetrates the outer nylon fabric, at least the first layer of floation foam and the inner nylon fabric. The stitching of the straps to the side of the jacket may also penetrate through to the inner nylon fabric, however, it is preferred that additional flotation foam be inserted in the chests and sides. In this instance, a reinforcing panel is inserted in the sides to receive the stitching.
In other words, where the vest jacket comprises a composite sandwich of an outer layer of nylon fabric, a first layer of flotation foam, a reinforcing panel in each side, additional layers of flotation foam in the chest pieces and the sides and an inner nylon fabric, the first and second straps may be attached to the left and right sides respectively on the outer nylon fabric by means of stitching penetrating and bonding together a strap, the outer nylon fabric, the first layer of flotation foam and the reinforcing panel at each side. The third and fourth o~
straps may be attached to the shoulder pieces by means of stitching penetrating and bonding together a strap, the outer nylon fabric, the first layer of flota-tion foam and the inner nylon fabric.
In order to adjustably connect the chest pieces to the shoulder pieces to fit the wearer of the safety harness, first ana second slip buckles may be attached to the top of the left and right chest pieces respectively.
The slip buckles are held by loops which pass through them. The end of the loops are attached in opposition to one another on the outer and inner nylon fabrics by means of stitching penetrating and bonding together the'lou~er nylon fabric, the first layer of flotation foam and the inner nylon fabric. The slip buckles are adapted to receive the third and fourth straps from the shoulder pieces which connect to the securing means by means of adjustment of the slip buckles along straps (3) and (4) the chest pieces may be adjusted in relation to the shoulder pieces to achieve a snug fit on the wearer in order to maximize the advantages of force distribution available from this invention.
In order to affect the putting on and taking off of the safety harness, it is desirable to provide a means by which the safety straps may be releasably connected, therefore, it is in the preferred embodiment of this invention one of the first and second straps slideably connect to the securing means and continues to a first clasp means and the other of the first and second straps terminates before reaching the securing means at a second clasp means that will releasably connect to the first clasp means to permit the first and second straps to be joined through the securing means during periods of use and to be opened for removal of the jacke-t.
Similarly, it is preferred that one of the third and fourth straps slideably connect to the securing means and continue on to a third clasp means while the other of the third and fourth straps terminate before reaching the securing means at a fourth clasp means that will releasably connect to the third clasp means to permit the third and fourth straps to be joined through the securing means during periods of use and to be open for removal of the jacket.
It is also preferred that the straps terminate at the clasps in an adjustable connection so that the straps may be adjusted in length to position the securing means as desired in relation to the vest jacket.
~ It is also preferred that the securing means ;i comprise a hook affixed to a base having openings therein to receive the straps in slideable connection. The hook is adapted to be connected to a rope on a sailing craft or the like and is particularly well suited to being connected to a rope attached to a boom of a sailboard as it permits quick release when that is desirable to change direction of the sailboard.

The preferred embodiment of this invention is shown in Figure 1. As illustrated it comprises a vest jacket (1) including as integral parts thereof a back (2~
having shoulder pieces (3), underarm sides (4), and chest pieces (5). The securing means (6) is held to the vest jacket (1) by means of a first strap (7), a second strap (8), a third strap (9), and a fourth strap (10). Straps (7) and (8) are stitched to the shoulder pieces, while straps (9) and (10) are stitched to the side pieces. None of the straps exténd around the back of the jacket so that the forces transmitted from the securing means (6) through the straps to the vest jacket is distributed through the shoulders and the sides throughout the back of the jacket.
Accordingly, localized pressure on the wearer of the jacket ~`
is minimized.
The securing means (6) is comprised of a hook (11) implanted in a base (12). The base (12) has a number of openings in it to receive in slideable connection the straps attached to the jacket. The chest pieces (5) are connected to the shoulder pieces (3) by means of straps (7) and (8) which are led through slip buckles (13) and (14) respectively.
Slip buckles (13) and (14) are held by loops (15) and (16) respectively. The ends of the loops (15) and (16) are stitched to the top of the chest pieces (5) on the inside " ~4~9Z
and outside of the jacket in opposition to one another.
The stitching securing them passes completely through the jacket as will be explained later in greater detail.
As illustrated in Figure l, the strap (8) from shoulder piece (3) passes through buckle (14) and through an upper opening in the base (12) of the securing means (6) to terminate at a male clasp member (17). Strap (7) leading from the other shoulder piece (3) passes through slip buckle (13) to terminate at female clasp member (18).
The clasp members (17) and (18) may be opened for putting the jacket on and taking it off and closed during use..
Similarly, strap (9) which is attached to side (4) is led through an opening in the base (12) of the securing means (6) to a male clas~ member (19) while the other strap (10) from the other side (4) is led to a female clasp member (20). Clasp members (19) and (20) permit straps (9) and (10) to be joined when the safety harness is in use and to be separated for removal of the jacket.

The preferred embodiment of this invention is shown in Figure 1. As illustrated it comprises a vest jacket (1) including as integral parts thereof a back (2~
having shoulder pieces (3), underarm sides (4), and chest pieces (5). The securing means (6) is held to the vest jacket (1) by means of a first strap (7), a second strap (8), a third strap (9), and a fourth strap (10). Straps (7) and (8) are stitched to the shoulder pieces, while straps (9) and (10) are stitched to the side pieces. None of the straps exténd around the back of the jacket so that the forces transmitted from the securing means (6) through the straps to the vest jacket is distributed through the shoulders and the sides throughout the back of the jacket.
Accordingly, localized pressure on the wearer of the jacket ~`
is minimized.
The securing means (6) is comprised of a hook (11) implanted in a base (12). The base (12) has a number of openings in it to receive in slideable connection the straps attached to the jacket. The chest pieces (5) are connected to the shoulder pieces (3) by means of straps (7) and (8) which are led through slip buckles (13) and (14) respectively.
Slip buckles (13) and (14) are held by loops (15) and (16) respectively. The ends of the loops (15) and (16) are stitched to the top of the chest pieces (5) on the inside " ~4~9Z
and outside of the jacket in opposition to one another.
The stitching securing them passes completely through the jacket as will be explained later in greater detail.
As illustrated in Figure l, the strap (8) from shoulder piece (3) passes through buckle (14) and through an upper opening in the base (12) of the securing means (6) to terminate at a male clasp member (17). Strap (7) leading from the other shoulder piece (3) passes through slip buckle (13) to terminate at female clasp member (18).
The clasp members (17) and (18) may be opened for putting the jacket on and taking it off and closed during use..
Similarly, strap (9) which is attached to side (4) is led through an opening in the base (12) of the securing means (6) to a male clas~ member (19) while the other strap (10) from the other side (4) is led to a female clasp member (20). Clasp members (19) and (20) permit straps (9) and (10) to be joined when the safety harness is in use and to be separated for removal of the jacket.
The construction of the preferred embodiment of the safety harness of this invention is shown in Figures
2, 3, 5, 6 and 7. The attachment of the side straps (9) and (10) is particularly illustrated in Figures 2 and 3.
In the first step in the construction of this preferred embodiment a piece of nylon fabric is cut to a pattern to form the outer shell (21) of a vest jacket. Then a similarly cut, but slightly undersized piece of flotation foam (22) is laid over the outer shell (21) reinforcing panels (23) are then paid over the flotation foam (22) at the sides (4).
These elements are pinned together and then straps (9) and (10) are stitched to the outside of the outer shell completely through the outer shell (21), the flotation foam (22) and the reinforcing panels (23) as illustrated in Figure 3.
`' ~ Z
Additional pieces of flotation foam (24) and (25) are then added over reinforcing panels (23) and the flotation foam (22) to provide additional cushioning and flotation for the jacket as is illustrated in Figure 4. This is then covered by an inner shell of nylon fabric (26) and the whole composite sandwich is sown toge~her by an initial stitching (29) about the perimeter as illustrated in Figure 5. The stitching of the perimeter is shown in Figure 6. The edge of the jacket is bound up by binding (28) which is a small piece of nylon fabric folded in upon itself and stitched to the perimeter by stitching (29) which passes through the bindingr the outer shell (21), the layer of flotation foam (22) and the inner shell (26). Then stitching (27) is made about an inch from the perimeter edge so as to again pass completely through the jacket. Then loops (15) and (16) with the slip buckles (13) and (14) are stitched to the top of the chest pieces (5) as illustrated in Figure 7. The ends of the loops (15) and (16) are placed adjacent to the outer and inner shell and stitched completely through the outer shell, -the flotation foam layer (22) and the inner shell (26). Then shoulder straps (7) and (8) are sown to the outer shell (21) by means of stitching which passes through the straps (7) and (8), the outer shell (21), the layer of flotation (22) and the inner shell (26).
Straps (7) and (8) are then passed through buckles (13) and (14) ` respectively and through the base of (12) the securing means (6) to terminate in clasps (17) and (18) as illustrated in Figure 1.
Similarly, (9) is led through base (12) of the securing means (6) to clasp (19) and strap (10) is led to clasp (2) as is also shown in Figure 1.
~ .
9z The preferred embodiment of this invention as constructed above may then be worn by a sailor to support him while operating a sailing craft such as a sailboard as illustrated in Figure 8. As illustrated the sailor (30) wearing the safety harness of this invention attaches the secure means (6) to a rope (31~ which in turn is attached to the boom (32) of the sailboard thus by leaning back in the jacket the weight of the sailor (30) pulls the sail (33) against the force of tlle wind thereby reducing the amount of exertion required of the sailor's arms. Because of the design of the safety harness of this invention the sailor (30) may maintain this position for long periods of time without discomfort caused by the forces exerted through the straps.
It will be appreciated that many modifications and alterations may be made to the preferred embodiment disclosed here without departing from the concept of the invention.
