Abstract
Abstract An apparatus for use in the design of ortopaedic chairs comprises a chair (2) and a contour measuring device (2a) mounted at the rear of the chair (2). The contour measuring device includes an elongate member (8) having a plurality of rods (9) slidably mounted therein, the rods (9) being mounted in parallel side-by-side relationship along the length of the elongate member (80) in a substantially common plane. In use, each rod (9) is slidable so as to enable the tip of one end of each rod (9) to engage the back of a patient sitting in the chair which tips thereby define a contour of the patient's back. A number of different contours along different vertical planes may be taken by adjusting the position of the elongate member (8) in the horizontal direction.

Claims Analysis
Total Claims: 22
Claim 1
Independent Claim
115 words
An apparatus for use in the design of orthopaedic chairs, the apparatus being characterised by a chair (2) and a contour measuring device (2a) positioned at the rear of the chair, the contour measuring device including a first elongate member (8) having a plurality of rods (9) slidably mounted relative thereto, the rods (9) being arranged in parallel side-by-side relationship along the length of the member (8) in a substantially common plane whereby, in use, each rod (9) is slidable so as to enable the tip of one end of each rod (9) to engage the back of a patient sitting on the chair (2) which tips thereby define a contour of the patient's back.
Claim 2
Independent Claim
115 words
An apparatus for use in the design of orthopaedic chairs, the apparatus being characterised by a chair (2) and a contour measuring device (2a) positioned at the rear of the chair, the contour measuring device including a first elongate member (8) having a plurality of rods (9) slidably mounted relative thereto, the rods (9) being arranged in parallel side-by-side relationship along the length of the member (8) in a substantially common plane whereby, in use, each rod (9) is slidable so as to enable the tip of one end of each rod (9) to engage the back of a patient sitting on the chair (2) which tips thereby define a contour of the patient's back.
