ABSTRACT:
A number of variations of a simple structure for leisure chairs appropriate for both serious indoor use as well as outdoor use. The structure comprises a backrest or occupant supporting member (2) that intersects with and is attached to a countersupporting member (4) in a manner that results in each bearing on the other. Embodiments are disclosed that include armrests (A.P.) as an integral part of the countersupporting member (4). The backrest member (2) is disclosed as straight, with a convex curve in the lower portion (L.P.) of the backrest member (2) to support an occupant's lumbar curve, with a bend between the upper and lower portion to orient the upper portion (U.P.) of the leisure chair at a higher angle than the lower portion (L.P.). A variety of methods of attaching the backrest member (2) to the countersupporting member (4) are disclosed, as are a number of ways of securing the leisure chair in an open position. Other embodiments are disclosed with a seat and legrest structure (3) attached to the occupant supporting member (2). Also disclosed are a couple of chairs with upholstery (12, 14 and 16) and miscellaneous finishing touches as examples of how the structure might be used in finished chairs.
