ABSTRACT:
FIELD OF THE INVENTION
The present invention is in the field of physical therapy devices and more particularly it is directed to an ergonomic knee support pillow that can be adjusted to a variety of heights.
1. Background of the Invention
Knee supports can provide relaxing comfort and support to the knees in a sitting or reclining position, particularly in instances of recovery from injury, disease, fatigue, etc. Most knee supports and/or knee wedges must remain in one set position. Others require that material layer and/or additions be added or removed to fit user comfort needs. This means that the user must leave the seated or reclining position to add to and/or adjust the wedge or support. Most of the supports or wedges are configured in a shape that only allows one or two set heights, depending on the size of the wedge that is used.
2. Discussion of Known Art
U.S. Pat. No. 5,878,453 to Stokes discloses a pillow for alleviating lower back pain including an under-knee portion which holds an individual's knee in flexion when he is lying on his back, and a between-knee portion, which hold the individual's knees a spaced distance apart when he lying on his side. Adjustment is provided for the relative positions of the two portions to accommodate users of different sizes.
U.S. Pat. No. 5,871,457 to Swedberg discloses a modular knee positioning support having at least one leg-engaging portion removably attached to a center wedge portion.
OBJECTS OF THE INVENTION
It is a primary object of the invention to provide a knee support that allows for an infinite variety of heights to be selected by the user.
It is a further object that the knee support can be deployed with the user in a reclining or seated position.
It is a further object that the knee support can be adjusted by the user without having to leave the reclining or seated position.
SUMMARY OF THE INVENTION
The above mentioned objects have been accomplished in the knee support of the present invention of a knee support pillow configured with an elliptical cross-sectional shape that allows for variable height and support by rotating or adjusting the unit into any desired height to support users' knees and legs. Handles built into the end of the support pillow act as easily grasped handgrips to facilitate rotating the unit forward and back to obtain an optimal comfort setting for the user. The user can position and adjust the support pillow while remaining in a seated or reclining position, and can re-adjust the support as needed to accommodate changing tasks or activities.
