## Background
CROSS-REFERENCE TO RELATED APPLICATION
This application claims the benefit of U.S. Provisional Application No. 61/616,624, filed Mar. 28, 2012.


FIELD OF THE INVENTION
The present invention relates to the sports field such as swimming or golfing, and in particular it relates to a device for use by a sportsperson to practice correct posture while performing a succession of body movements.
BACKGROUND OF THE INVENTION
The movement that a swimmer executes while swimming is called a “stroke”, a variety of strokes exist which require the coordination of multiple body parts in a rhythmic fusion. Similarly the series of movement a golfer executes to strike a golf ball is called a “swing” and a compound of body movement's results in a successful shot.
The compound of coordination required for a stroke or a swing is complicated by an individual's habits and athletic ability.
A stroke can be seen as a succession of positions and actions. For strokes such as the front crawl, butterfly and the breast stroke there is an optimal succession of movements which result in the most efficient performance of the stroke. One critical component for performing these strokes is the posture of the head and neck while swimming. The swimmer needs to keep their head down, which in turn forces their hips up, allowing a more hydrodynamic and efficient stroke. Swimmers have a tendency to lift their heads in the water, without realizing it forces their hips down, creating increased drag. With a head up posture, their stroke will no longer be optimal and their efficiency will suffer.
Various training aids exist for improving performance while swimming. There are a variety of hand paddles, kick boards, stretch cords, and drag chutes available for training.
Other equipment used by sportspersons for practice comprises sophisticated and expensive devices such as sensors which are attached to a person, or use a video camera for checking and adjusting the movement.
However, the above described equipment and other training equipment for sportspersons are not adapted to assist in keeping the head down, achieving the correct posture of the head and neck.

DESCRIPTION OF PREFERRED EXEMPLARY EMBODIMENTS
In accord with FIG. 1, a training device for sportspersons, according to the invention, which can be used by a sportsperson to train a correct succession of movement, comprises a head support 1 having a tailpiece 2.
In detail, the head support provides a strap mounting feature 3 that is equipped with a plurality of openings 4 for a head strap 5, and scalloped portion 6 of the head support to accommodate a hair bun or pony tail, the training device with respect to which the sportsperson wears in a corresponding position during the performance of a stroke, a swing, or other sport.
Furthermore, as shown in FIG. 2 the head support 1 and tailpiece 2 are provided at an angle which accommodates the sportsperson's activity. The angle of the tailpiece determines the degree of freedom the sportsperson has in performing a movement. The curvature of the training device in FIGS. 1 and 2 is defined by angle α and β, shown in FIG. 7. Advantageously the training devices of the invention may have an α angle from 270° to 45° depending on what is appropriate for the activity of the sportsperson. The α angle can be between 45° and 270°, advantageously between 90° and 180°, advantageously between 100° and 170°, advantageously between 120° and 150°, and advantageously between 137° and 140°. The α angle is most preferably approximately 137°. The β angle is defined as the difference of the angle of the training device tailpiece centerline 9 as compared to a tailpiece 2 with an α of 140°. The β angle can be between −90° and 90°, advantageously between −70° and 70°, and advantageously between −50° and 50°, advantageously between −30° and 30°, advantageously between −20° and 20°, advantageously between −10° and 10°, advantageously between −5° and 5°, and advantageously between −3° and 3°, and most preferably 3°.
More in detail, the invention provides for alignment of the head support and tailpiece. Most activities require the training device to be worn on the head so that it is evenly positioned relative to the trainee's head, neck and shoulders, requiring proper registration of position. There are several ways to achieve a correct registration of the position of the head support 1 and tailpiece 2. FIG. 6 depicts a strap 5 for use with a head support 1 held in place by strap mounting features 3. The trainee can align the head support and tailpiece on their head by feeling where the buckles 10, as shown in FIG. 3, are positioned on their head.
The combination of the body's own exteroception and proprioception gives a trainee the ability to feel when something is evenly held relative to the other parts of their body. Advantageously, the buckles 10 of head strap 6 provide a key for proper registration, as well as making it convenient to attach and detach the training device from the strap of swimming goggles.
In accord with FIG. 8, the head registration of the training device may be facilitated by bumps or raised portions 11 of the strap 5.
In addition or alternatively the invention as in FIG. 8 through 12 may be composed of a head support and tailpiece inserted into a strap with a special head strap pocket 12 to accommodate the device.
A further variation of the invention allows for the head support 1 and tailpiece 2 element to be detachable from the head strap 5 as in FIG. 13 and FIG. 14. The advantage of the removable head support 1 and tailpiece 2 allows the trainee to use tailpieces of different lengths or head supports of different shapes. Furthermore, the head strap pocket 12 version of the head strap 5 provides enhanced registration of the device for alignment on the head.
In addition, FIG. 15 through FIG. 18 show a profile view of various configurations of the invention used with swimming goggles 13. As in FIG. 18 the training device uses a discreet head strap 5 criss-crossed underneath the strap from the swimming goggles 13. FIG. 17 shows the head strap of the training device and swimming goggles head strap where the training device head strap is on top of and overlapping the head strap for the swimming goggles. While in FIG. 16. the training device uses the same head strap as the swimming goggles, and FIG. 15 shows the same with a swimming cap in place.
In particular, FIG. 19 shows the training device in a typical position for use by a swimmer. This arrangement is demonstrative and is not meant to limit the possible uses of the training device. The head support 1 is held to the trainee by head strap 5 high enough on the back of the head that it allows the tailpiece 2 to clear the shoulders when the trainee turns their head to the side to breath while still keeping the tip of the tailpiece proximate to the shoulder blades so that if the trainee inadvertently lifts his head the tailpiece will contact between the shoulder blades, providing a stimulus for the trainee to correct their head posture.
In one embodiment, as in FIG. 20 the invention features a head strap with ear registration pieces for accurate alignment of the training device.
In addition, or alternatively, FIG. 21 and FIG. 22 show the training device worn with a swimmers cap. In FIG. 22, the training device has registration points 11 on the strap.
