BACKGROUND OF THE INVENTION 
       [0001]    1. Technical Field 
         [0002]    The present invention relates to a ski training harness for children, which has a pair of retractable leashes. 
         [0003]    2. Description of Related Art 
         [0004]    Ski training harnesses for children are known in the art. These harnesses typically have a strap which attaches to the harness, allowing an adult skiing behind a child to control the child&#39;s downhill speed and direction. 
         [0005]    However, ski training harnesses in common use have several disadvantages. For example, some harnesses have a strap that attaches to the harness at the upper back portion, rather than at the waist. These are less suitable for small children because when an adult tugs on the straps they often cause the child to fall backwards. Other harnesses have strap attachment points only at the left and right sides of the waist. This is fine for teaching children to ski, but is not useful for teaching a child to snowboard. Also, the straps of the ski harnesses described to date are of a fixed length. This presents issues with respect to both convenience and safety when the strap is not in use, such as when the child is preparing to get on a chair-lift or gondola. At that point the strap, which is typically 10-20 feet long, either must be rolled up or disconnected from the harness, and held by either the child or an adult assistant. In either case, much care must be taken to ensure that the strap not be allowed to drop or become unrolled as either event can cause a serious safety hazard. 
         [0006]    U.S. Pat. No. 4,424040 describes a ski training halter adapted for positioning on a person below his or her waist and to extend across the person&#39;s front, lower abdominal region to the respective left and right hip regions of the student&#39;s body. The training halter also includes portions adapted to be positioned around the upper portions of the student&#39;s thighs and interconnected with the portions extending across the student&#39;s lower abdominal and hip regions. Adjustable and detachable fasteners are provided to maintain the training halter in proper, taut position on the person&#39;s body, and elongated reins are detachably connected to the training halter and extended to a location rearwardly of the person where another person can be positioned safely on skis to hold the reins and use them to exert restraining and turning forces on the training halter. 
         [0007]    U.S. Pat. No. 5,074,795 describes a method for teaching children to ski using a wide torso encircling band and two pairs of reins of different length. At an early stage of learning, the instructor straddles the child and uses short reins to directly control the speed and direction of the child and the pair of ski slowly. At a later stage of learning, the instructor backs away from the child and uses the long reins to directly control the child&#39;s speed and indirectly control the child&#39;s direction. 
         [0008]    U.S. Pat. No. 5,080,191 describes a harness for use by adults or children in learning certain sporting activities such as snow skiing wherein handles are conveniently disposed for gripping by individuals helping a user of the harness. The harness is provided with unique means for positively positioning the harness on a user for optimal control. 
         [0009]    Retractable pet leashes provide for variable attachment, in distance, between a pet and the owner. These devices typically have a wind-up spool disposed in a housing with a thumb-actuated brake for controlling the amount of leash to be dispensed. 
         [0010]    For example, U.S. Pat. No. 4,501,320 describes a hand-held apparatus which dispenses, retracts and locks an animal leash in a desired position. The apparatus includes a spool housing sized to store a length of cord and a handle portion adapted to be grasped in the hand of a user. The spool housing rotably mounts a spool having the length of cord wrapped thereabout with the distal end of the cord being attachable to an animal collar. A coil spring is mounted between the spool and spool housing to continuously bias the length of cord in a retracted position about the spool. A high strength locking mechanism adapted to selectively apply friction to the spool and positively prevent the cord from being dispensed or retracted from the spool is provided which is actuable by way of a trigger lever formed on the handle portion of the housing. A cam actuator stop is additionally provided to maintain the locking mechanism in a locked orientation. 
         [0011]    Also, U.S. Pat. No. 6,688,260 describes a retractable pet leash that can alternatively be held in a user&#39;s hand or secured to a belt worn around the user&#39;s waist. The leash is retractable inside an enclosure designed to conform generally to the shape of a user&#39;s hip or waist. The retractor retracts a first length of leash that has a first connector coupled to its distal end. The first connector can be coupled to a second connector that is coupled to a handle portion of a second length of leash. The connectors allow the user to disconnect the second length of leash from the retractor. 
         [0012]    There exists a continuing need for a ski training harness having retractable leashes which may be safely and conveniently secured to the harness when not in use. Ideally, given the increased popularity of snowboarding, the ski training harness also should be adapted such that it is equally useful in teaching children to snowboard. The present invention substantially fulfills this need. 
       SUMMARY OF THE INVENTION 
       [0013]    The present invention is directed to a ski training harness comprising: (a) an adjustable, releasable waist strap extending horizontally around the waist of a child, the waist strap comprising closure means at each of its two terminal ends for securing the waist strap to a child; (b) a pair of adjustable, removable shoulder straps connected to the waist strap at a front and rear location relative to a child and adapted to extend over a child&#39;s shoulders; (c) a back strap interconnecting the shoulder straps at the back of a child, wherein the back strap comprises a handle adapted to allow an adult wearing ski gloves to easily grasp the handle; (d) an adjustable, releasable chest strap interconnecting the shoulder straps at the chest of a child; (e) a pair of adjustable leg straps having opposite ends connected to the waist strap at a front and rear location relative to a child, wherein each of the leg straps is adapted to enclose a child&#39;s leg; (f) a pair of retractable leashes connected to the waist strap at a left-side and right-side location relative to a child, wherein each of the retractable leashes comprises a handle adapted to allow an adult wearing ski gloves to easily grasp the leash handle, a portion of each of said leashes extending from each of said handles; and (g) means for securing the pair of leash handles to the waist strap.
