Abstract
Abstract Custodial protective structure for severely handicapped children subject to involuntary spastic responses is disclosed. A body support, formed from an elastically resilient material such as foamed rubber or vinyl, provides a body mold cavity establishing relaxed positional support and provides limited yielding in the event of seizure. A stabilizer holds the body support to limit longitudinal yielding and prevent asymmetric twisting of the body support while allowing access for handling and therapy; the stabilizer framework facilitates canting of the structure or mounting for swinging movement.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
153 words
Custodial protective structure for handling and therapeutic purposes for an individual subject to involuntary reflex responses, such as extensor thrust, comprising an elongated resiliently yieldable body support, such body support having a longitudinal axis and a centrally-located transverse axis, and defining a flexible body mold cavity which provides relaxed positioning over the full length of the body of an individual within such body support, such defined body cavity including a transverse concave portion for minimizing shoulder retraction, such concave portion being located for contact across the back at shoulder level of an individual within such defined body cavity, and stabilizing means for such body support including longitudinal end wall means for restraining and limiting longitudinal expansion of the defined body cavity, lateral support means extending between such longitudinal end wall means to prevent asymmetrical twisting of such yieldable body support about its longitudinal axis, and bottom support wall means for such body support.
Claim 2
Dependent Claim
153 words
Custodial protective structure for handling and therapeutic purposes for an individual subject to involuntary reflex responses, such as extensor thrust, comprising an elongated resiliently yieldable body support, such body support having a longitudinal axis and a centrally-located transverse axis, and defining a flexible body mold cavity which provides relaxed positioning over the full length of the body of an individual within such body support, such defined body cavity including a transverse concave portion for minimizing shoulder retraction, such concave portion being located for contact across the back at shoulder level of an individual within such defined body cavity, and stabilizing means for such body support including longitudinal end wall means for restraining and limiting longitudinal expansion of the defined body cavity, lateral support means extending between such longitudinal end wall means to prevent asymmetrical twisting of such yieldable body support about its longitudinal axis, and bottom support wall means for such body support.
Claim 3
Dependent Claim
78 words
The structure of claim 1 in which the stabilizing means includes elongated strongback means extending longitudinally the full length of such body support for holding the longitudinal end wall means in fixed positional relationship, such strongback means being located externally of such bottom wall means in relation to such body support and extending longitudinally beyond such longitudinal end wall means with such longitudinal extensions including preshaped distal ends for positioning such stabilizing means in canted relationship to vertical.
Claim 4
Dependent Claim
46 words
The structure of claim 2 in which such lateral support means include planar side wall members extending from longitudinal end wall means toward the centrally-located transverse axis, such side wall members decreasing in height in extending from such longitudinal end wall means toward such transverse axis.
Claim 5
Dependent Claim
29 words
The structure of claim 3 in which such lateral support means include side wall bracing members, and means for adjustably positioning such bracing members above such bottom wall means.
