Abstract
Abstract A device for positioning a patient in a chair having a back and arms. The device includes a pad for placement against the patient and a clamp which underlies an arm of the chair and is shiftable along the length of the arm independently of the back. The pad is connected to the clamp by a series of connecting members which permit universal swinging of the pad about a plurality of angularly disposed and laterally spaced axes. The pad also is mounted for shifting laterally of the attaching clamp and the arm to which it is attached and for shifting vertically and horizontally forwardly and rearwardly relative to the chair. Locking mechanism is provided for securing the pad in any of the infinitely selectable positions for the pad to maintain patient positioning within the chair. A similar pad attached to the opposing arm on the chair also may be used to aid in patient positioning.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
109 words
A device for positioning a patient in a chair having a back and arms, said device comprising body engaging pad means, attaching means for attachment to the underside of an arm of the chair and for movement along said arm toward and away from the chair back, means for securing said attaching means in a selected position on said chair arm, connecting means operatively connecting said pad to said attaching means accommodating universal movement of the pad relative to said attaching means to place said pad in a selected position relative to said chair for patient positioning, and securing means for securing said pad in a selected adjusted position.
Claim 2
Independent Claim
109 words
A device for positioning a patient in a chair having a back and arms, said device comprising body engaging pad means, attaching means for attachment to the underside of an arm of the chair and for movement along said arm toward and away from the chair back, means for securing said attaching means in a selected position on said chair arm, connecting means operatively connecting said pad to said attaching means accommodating universal movement of the pad relative to said attaching means to place said pad in a selected position relative to said chair for patient positioning, and securing means for securing said pad in a selected adjusted position.
Claim 3
Dependent Claim
45 words
The device of claim 1, wherein said attaching means comprises a clamp slidably mounted on said chair arm and said means for securing said attaching means comprises means for clamping said clamp to said arm to frictionally hold the same against movement along said arm.
Claim 4
Dependent Claim
77 words
The device of claim 1, wherein said connecting means comprises a first member mounted on said attaching means for rotation about a substantially horizontal axis extending substantially parallel to and underlying said arm, a second member connected to said first member and underlying said arm for rotation about a substantially upright axis, and a third member underlying said arm and connected to said second member for rotation about a substantially horizontal axis extending transversely of said arm.
Claim 5
Dependent Claim
40 words
The device of claim 3, wherein said third member comprises an elongate, substantially horizontally disposed element slidably connected to said second member for selected extension and retraction relative to said second member in a direction extending laterally of said arm.
Claim 6
Dependent Claim
50 words
The device of claim 4, which further comprises an elongate fourth member connected adjacent one of its ends to an end portion of said third member and extending outwardly therefrom at a substantial angle relative to the rotational axis for said third member and being swingable about said rotational axis.
Claim 7
Dependent Claim
77 words
The device of claim 5, which further comprises an elongate slide member, means pivotally connecting said slide member to said fourth member adjacent a set of ends of said fourth member and said slide member, and means connecting said pad means to said slide member permitting sliding movement of said pad means longitudinally of said slide member and swinging of said pad means relative to said slide member about an axis extending transversely of said slide member.
Claim 8
Dependent Claim
32 words
The device of claim 5, wherein said means connecting said pad means to said slide member is spaced more closely to one edge of said pad means than to other edges thereof.
Claim 9
Dependent Claim
25 words
The device of claim 7, wherein said securing means comprises detent means operable to produce positive locking of said pad means in a selected position.
Claim 10
Dependent Claim
85 words
The device of claim 1, wherein said attaching means comprises a clamp member attachable to the underside of an arm for movement longitudinally thereof, and said connecting means comprises means connected to said clamp member underlying said arm and supporting said pad means for swinging about a first axis which extends substantially horizontally beneath and substantially parallel to said arm, a second axis extending substantially vertically and intercepting said arm, and a third axis extending substantially horizontally beneath said arm and transversely of said arm.
Claim 11
Dependent Claim
38 words
The device of claim 9, wherein said connecting means further comprises means mounting said pad means for swinging about a fourth axis which extends substantially horizontally and transversely of said arm and is spaced from said third axis.
Claim 12
Dependent Claim
42 words
The device of claim 10, wherein said connecting means further comprises means mounting said pad means for rotation about a fifth axis extending substantially horizontally and transversely of said arm, with said fifth axis being spaced from said third and fourth axes.
Claim 13
Dependent Claim
35 words
The device of claim 11, wherein said connecting means further comprises an elongate slide member on which said pad means is slidably mounted accommodating adjustment of the distance between said fourth and fifth pivot axes.
Claim 14
Dependent Claim
18 words
The device of claim 12, wherein said fifth axis is spaced from the center of said pad means.
Claim 15
Independent Claim
255 words
A device for positioning a patient in a chair having a back and arms wherein an arm has an inner side facing generally in the direction of a patient and an outer side facing away from the patient receiving region, said device comprising body engaging pad means, attaching means for attachment to the underside of an arm of the chair and for movement along said arm toward and away from the chair back, means for securing said attaching means in a selected position on said chair arm, connecting means operatively connecting said pad to said attaching means accommodating universal movement of the pad relative to said attaching means to place said pad in a selected position relative to said chair for patient positioning, said connecting means comprising a substantially horizontally disposed elongate tubular member pivotally connected adjacent one of its ends to said attaching means, and an elongate shaft mounted removably and slidably in said tubular member for selected longitudinal adjustment relative thereto to permit adjustment of said pad means laterally of said arm, said elongate tubular member being swingable about said upright axis to a first position in which it extends in the direction of the inner side of the arm to permit adjusting said pad means to a position furthest from said arm and a second position extending in the direction of the outer side of the arm to permit adjusting of said pad means to a position nearest to said arm with minimum structure extending beyond said outer side of the arm.
Claim 16
Independent Claim
