Progressive flexible tabs on orthotic devices
View Patent ↗The orthotic device for the restraint of a portion of the human body has flexible tabs at the edges of its principal panel. The flexible tabs are substantially rectangular in outline to maximize support area, but are tapered in cross-section substantially between the base and tip or otherwise configured to increase the flexibility of the tabs toward the tip to aid in comfort at the transition.
1. An orthotic device comprising:
a panel for engagement around a body part to be constrained, said panel having an edge with first and second tabs separated by a notch, each of the tabs easier to flex near its tip than near its base, and where such differences in flexion are apparent while the device is being worn; and
wherein said tab is of substantially uniform thickness and there are openings therein substantially in the configuration of a triangle having its apex towards said base of said tab.
2. The orthotic device of claim 1 further comprising a padding layer on one side of said panel and said tab engages said padding layer.
3. The orthotic device of claim 2 further comprising a tightener structure engaging on each end of said panel.
4. An orthotic device comprising:
a panel for engagement around a body part to be constrained, said panel having edges and ends, and notches in at least one of said edges to define tabs along that edge, said panel and tabs being made of a synthetic polymer composition material having substantial flexibility while being worn, with said tabs having a base at said notches and a tip away from said base, said panel having an inside surface, a padding layer against said inside surface, said padding layer extending past said edges of said panel, said tabs being configured to have reduced bending strength adjacent said ends of said tabs than towards said base of said tabs said tabs are progressively flexible under load from said padding layer so as to ease the transition between the restrained and unrestrained portion of the body; and
wherein said panel is of substantially uniform thickness and there is a substantially triangular opening in each of said tabs so that the total cross-section of each of said tabs is progressively lesser towards said tip from said base.
5. The orthotic device of claim 4 wherein said opening is substantially in the configuration of an isosceles triangle having its apex directed towards said base.
6. The orthotic device of claim 5 wherein said panel is stamped from a sheet of synthetic polymer composition material of substantially uniform thickness.
