The present invention relates to a backrest device, and more particularly to a backrest device for supporting the lower part of the back of a person in a sitting position.

When a person sits upright on a flat surface without a curved backrest, such as a floor, a floor or a chair without a backrest, such a position becomes uncomfortable and felt. This discomfort does not support the lower back, so poor posture or weak people feel discomfort in a relatively short time.

Meditators, such as yoga and other similar exercises, should sit up straight for a long time. Many sporting activities, including canoeing and hunting in fixed shelter, also require sitting for long periods of time, resulting in the above inconvenience. In the case of the above activities, they have to sit upright for long periods of time, thus requiring a simple and inexpensive device that can provide the backrest necessary for making the above activities comfortable.

Backrests and similar support devices are described in Ziegler, U.S. Patent No. 1,226,375, Boehringer's Swiss Federal Patent No. 259,006, McConnell's British Patent No. 188,750 and Australian Patent No. 28,347.

The backrest device according to the present invention includes a pocket that is formed to form a rectangular backrest member of a suitable dimension that is deployed to support the waist of the user. The backrest includes a pair of non-stretchable straps, which extend in the longitudinal direction from the end of the backrest member and have a ring-shaped structure that can cover the knees of the user in the seated position described above. The strap further includes an adjustable knee pad installed on the strap to wrap around the user's knee. Each strap includes an appropriate buckle adjusted to fit the length of the strap according to the size of the individual's physique. Buckle means are connected to relax the muscles of the inner leg of the user to keep the two loops in one.

It is an object of the present invention to provide a backrest device that allows a user to sit upright comfortably for a long time without the backrest of the back.

Another object of the present invention is to provide a lower back support such as being made to be worn by a person sitting on the floor or in a backless chair or bench in an upright position with their legs crossed or without their legs crossed.

Still another object of the present invention is to provide a flexible backrest device that can be applied to various kinds of sitting postures and can be adjusted to fit an individual's physique.

1 shows a backrest device 10 according to the present invention, the backrest device 10 wraps the lower back part of the wearer as shown in FIGS. 2 and 3 to cover the waist of the wearer's back.

The backrest device 10 in this embodiment consists of an unfolded pouch 12, which preferably consists of a generally rectangular member 14 made of a strong textile material, such as a tent or belt material. The rectangular member 14 has a length that surrounds the lower back part of the user and a width that extends to the height of the waist part. The backrest device 10 may include a foam cushion disposed between two layers of fabric material to mitigate the impact.

A pair of elongated straps 16, 18 forming a loop is attached to the rectangular member 14 by any suitable conventional method such as sewing or the like. Each strap 16, 18 includes an adjustable buckle 20, 22, respectively. Although the buckle is shown in a snap-in type, it will be appreciated that any type of buckle fastener may be used in the construction of the present invention, including hook-loop separating fastener assemblies. The straps 16 and 18 include long knee pads 24 and 26 where the support loops 24 and 26 are secured in the proper positions of the straps 16 and 18. This allows the knee pads 24 and 26 to slide along the length of the straps 16 and 18. In use, the knee pad covers the user's knee and leg portions. The straps 16 and 18 are made of a flexible, non-stretch material with sufficient strength to support weight in use.

The backrest device 10 further includes a buckle indicated by reference numeral 28. The buckle 28 is composed of a male member 30 and a female member 32, the male member 30 is slidably connected to the strap " 16 " and the female member 32 can slide on the strap " 18 ". Is connected. The buckle 28 serves to connect the strap 16 and the strap 18 to each other in a manner that allows for relaxation of muscle tension between the user's legs.

Referring to Figures 2 and 3, the backrest device 10 is placed against the waist of the back when the user takes one of the various sitting positions. The long straps 16 and 18 loop around the knees and the pads 24 and 26 are secured to the straps 16 and 18 so as to slide around the knees as shown.

It is shown in FIG. 4 that the backrest device 10 further comprises a retainer strap 40, which allows the long strap to hold the backrest in place without the need for the long straps to loop the knees. In order to wear the backrest device 10 on the back, the position is fixed by the adjustment buckle 42 surrounding the user's torso. Of course, this is not supportive, but there is no need to readjust the position of the backrest device 10 every time it is used, and it is also necessary to care about fixing the backrest device 10 to an appropriate position during the wearing process. Facilitate the process of wearing long straps 16 and 18 on the user's knees without. In addition, this facilitates the transport of the backrest device 10 since there is no need to carry a separate carrying case or carry the case all the time. The user may not wear straps 16 and 18 on the knees during sporting activities such as rowing, canoeing, motorcycling or hunting, and for other activities wearing the straps.

FIG. 5A shows the backrest device 10 being folded to form a pocket 12 therein that requires straps 16 and 18 therein, and FIG. 5B shows the pocket locked by the zipper 50. FIG. Indicates. Two handle rings " 54 " and " 54 " are preferably provided at the end of the rectangular member 14 for easy transportation by the user.

The two handle hooks 54, 54 are coupled to a suitable fastener means to serve as retainer straps adapted to surround the user's waist so that the backrest 10 can be held in the user's lower back. do.

The structure can be modified and changed, such as for example a backrest device consisting of a complete unitary structure with integrally attached straps. The backrest device may also be composed of inflexible or slightly flexible parts, and for certain individuals the backrest may be specifically adapted to their body shape. The backrest device 10 may also be composed of a plurality of strap portions without departing from the scope of the present invention, which is defined by the following utility model registration claims.
