1. Field of the Invention
This invention relates generally to safety and restraint equipment to keep a person safely still during a professional service, and specifically adjustable safety harnesses for use on children when having their hair cut.
2. Description of Related Art
The prior art describes many devices for preventing children from falling from various seated heights, such as chairs, strollers, highchairs and grocery carts. Many of these devices are complex, cumbersome and expensive to manufacture. No prior art, however, was located that was designed specifically for, nor was suitable for, use in a professional services chair, such as a hydraulic chair. The prior art child safety harnesses are designed primarily to prevent the child from falling, or escaping. Because the prior art harnesses are geared more toward the prevention of falling, or actual escaping, they are bulkier, more restrictive and more complex than what would be appropriate for use to restrict the movement of a person in a professional services chair.
The prior art includes U.S. Pat. No. 7,073,866 directed to a fully adjustable universal safety harness or restraint for small children, designed to secure them in various chairs, high chairs, booster seats, shopping carts or strollers, or to control their movement. The restraint has a harness which fits over the child's shoulders and fully wraps around the chest and waist, including a separate strap, swivel hooks, belt loops and several D rings. U.S. Pat. No. 6,095,613 entitled Multi-Purpose Child Safety Harness is directed to a harness that is wearable and is used to support, hold, restrain, and protect a child during a variety of the child's activities. The harness includes a torso band, a pair of shoulder straps, an inner crotch strap, an outer crotch strap, and underarm securing straps. Once again the waist belt portion fully covers the lower torso and is quite restrictive.
These and similar patents involve restraints with numerous or complex parts that are relatively bulky and restrictive to the user. They are not designed to fit a professional services chair. They are not specifically designed to keep the child or person still, while minimally restraining them, so they can safely undergo a professional service or procedure.
The disadvantages shown in the prior art are solved by the disclosure herein of a simple adjustable harness restraint, specifically designed to keep the person safely still while in a professional services chair, such as a hydraulic chair, while undergoing a procedure, such as a haircut. During a professional services visit, such as a dentist appointment or a haircut in a salon, professionals work with the person using potentially sharp instruments. It is imperative that the person feel safe, comfortable and minimally restrained, yet that the person be kept still so the professional can perform the procedure. As an example, it is very difficult for a hair stylist to cut a child's hair while the child is wriggling, twisting and turning in the salon chair.
To overcome the gaps in the prior art, the disclosed invention depicts an adjustable harness for restricting a person's movement while in a professional services chair. The harness is primarily targeted for small children, in order to restrict their movement enough to allow the professional to complete the procedure safely and quickly. The harness could also be used, however for mentally or physically challenged older children or adults, who may have difficulty restricting their own movements.
More particularly, the harness is minimalistic, comprising only five straps, none of which are bulky. In its minimalistic design, the harness is more similar to a seatbelt than to the prior art harnesses seen in the prior art, several of which fit over the child or person's head like a straitjacket.
The minimalist approach offers several advantages. First, the simple straps do not feel overly restrictive, bulky or binding to the wearer. This is important as children or those who are mentally or physically challenged are more likely to wear the harness as a result of its comfort and simplicity. Second, the harness, due to its simple design that simply straps the person to the chair, is extremely easy to apply and remove; literally only taking seconds. Again this is important as the target classes described above are unlikely to exhibit much patience while the professional is attaching or removing the harness. Because the strap system of the harness is somewhat similar to a seat belt or car seat harness, it should look and feel familiar to the child or person, encouraging acceptance.
Third, the harness, not having a great deal of surface area, is easy to keep clean.
Fourth, the harness is specifically created to accommodate not only a hydraulic chair, but also a booster seat, which children often sit on while in the hydraulic chair, undergoing a procedure such as a haircut or dental procedure.
In the preferred embodiment, the harness comprises a waist strap, a crotch strap, two shoulder straps, and a front cross strap. The waist strap travels across the child's waist, encircling the chair with the two ends coupling together behind the chair using an adjustable slide fastener. The crotch strap is sewn to the front midpoint of the waist strap and travels vertically down between the child's legs, under the booster seat (if one is used) and then up the posterior back of the chair, where it couples to the rear midpoint of the waist strap by an adjustable fastener.
Two shoulder straps are sewn to the front of the waist strap, one on either side of the crotch strap. The shoulder straps travel up the front of the person's torso and continuing over the person's shoulders. The shoulders strap travel down the person's back in a criss-cross or X pattern. At the middle point of the X, the shoulder straps pass through a slidable D or O ring which holds the straps in place. The shoulder straps continue down and couple to the rear of the waist strap with two adjustable fasteners.
The front cross piece holds the shoulder straps in position and keeps them from sliding off the person's shoulders. The front cross piece may be permanently sewn to the shoulder straps or each end of the front cross piece may be folded over the width of the shoulder straps and the ends of the cross piece sewn to itself to create a loop for the shoulder straps to pass through.
Other advantages of the present invention will become apparent from the following descriptions, taken in connection with the accompanying figures, wherein, by way of illustration and example, an embodiment of the present invention is disclosed.
The application makes no claim for the structure of the objects depicted in the photos and drawings, such as a hydraulic chair and booster seat, with which the harness is used, and they are considered prior art.
For a detailed description of various embodiments, reference will now be made to the accompanying figures and photos in which:
Certain terms are used throughout the following description to refer to particular system components. As one skilled in the art will appreciate, design and manufacturing companies may refer to a component by different names. This document does not intend to distinguish between components that differ in name but not function.
In the following discussion, the terms “including” and “comprising” are used in an open-ended fashion, and thus should be interpreted to mean “including, but not limited to . . . .”Also, the term “couple” or “couples” is intended to mean either an indirect or direct connection. Thus, if a first device couples to a second device, that connection may be through a direct connection or through an indirect connection via other intermediate devices and connections. Moreover, the term “system” means “one or more components” combined together. Thus, a system can comprise an “entire system” or “subsystems” within the system. “Adjustable fastener” may include adjustable slide buckles, double rings, slidable rings, or any other appropriate device to adjustably fasten two ends of a strap.
Turning to the drawings,
Further depicted in
To apply the harness to the person, the professional simply lays the crotch strap vertically over the seat cushion of the chair, placing the booster seat over the crotch strap portion and letting the remainder of the front of the harness dangle down in front of the chair. The posterior end of the crotch strap emerges at the posterior back of the chair, between the back cushion and the seat cushion, or, if the two are sewn together, the crotch strap travels under the whole chair rather than just under the booster seat.
In the case of a child who needs a booster seat, the child is placed on the booster seat and the professional lifts the harness over their head, settling the shoulder straps on the child's shoulders and letting the waist straps fall to the child's sides. In no particular order, the professional couples the waist straps together behind the chair, tightening or loosening as necessary. The professional couples the shoulder straps to the waist strap, again, tightening or loosening as necessary. The professional couples the crotch strap to the waist strap, again tightening or loosening as necessary.
Upon completing the procedure, the professional need only uncouple the waist strap and crotch strap, lifting the harness off the child or person. The same application and removal process applies for taller children or persons who do not need a booster seat.
The straps can all be made of woven cotton, nylon, or natural or artificial fiber fabrics, which can be manufactured by standard techniques, known to those skilled in the art.
In the preferred embodiment, the harness encourages the child or person to be still as the professional performs the procedure, which may include procedures such as hair cuts, various salon treatments, dental examinations and treatments, optometry exams and other professional services where a child or person needs to be still in a seated position.
In the preferred embodiment, the child is less able to wiggle, twist and move but is comfortably and simply restrained.
The disclosure is intended for children or persons able to sit up on their own. It could be used in a variety of professional services chairs, including hydraulic chairs. It could also be used in wheelchairs to prevent a child or person from sliding down in the wheelchair.
While the disclosed harness has been described in conjunction with the preferred embodiments thereof, many changes, modifications, alterations and variations will be apparent to those skilled in the art. Thus, although the invention is described in conjunction with restraining a child in a professional services chair, such as a hydraulic chair, it is also applicable to safety harnesses for restraining children in other situations.
Accordingly, the preferred embodiments of the invention shown in the drawings and described in detail above are intended to be illustrative, not limiting, and various changes may be made without departing from the spirit and scope of the invention as defined by the claims set forth below.
This application claims the benefit of provisional patent application 61/110,815 filed Nov. 3, 2008 by the present inventor and the application is hereto incorporated by reference in its entirety.
