Claim 1
Independent Claim
159 words
A bed having: a frame; body support means; the body support means having upper and lower body support sections; the body support means being horizontal on the frame in a sleeping position to provide a flat sleeping surface; the upper body support section selectively movable relative to the frame from the sleeping position to a tilted sitting-up position; two adjacent slats extending across the bed between the upper and lower body support sections forming a buttock receiving depression when the upper body support section is moved from its sleeping position to a tilted sitting-up position; means for maintaining the slats horizontal in the sleeping position and means for moving the slats to a shallow V-position to form the depression when the upper body section moves to a tilted sitting-up position, the means maintaining the slats horizontal comprising a portion of the upper body support section extending under the slats when the body support means is in a sleeping position.
Claim 2
Dependent Claim
159 words
A bed having: a frame; body support means; the body support means having upper and lower body support sections; the body support means being horizontal on the frame in a sleeping position to provide a flat sleeping surface; the upper body support section selectively movable relative to the frame from the sleeping position to a tilted sitting-up position; two adjacent slats extending across the bed between the upper and lower body support sections forming a buttock receiving depression when the upper body support section is moved from its sleeping position to a tilted sitting-up position; means for maintaining the slats horizontal in the sleeping position and means for moving the slats to a shallow V-position to form the depression when the upper body section moves to a tilted sitting-up position, the means maintaining the slats horizontal comprising a portion of the upper body support section extending under the slats when the body support means is in a sleeping position.
Claim 3
Dependent Claim
