Upholstered seat with flexible pelvic support

摘要

An upholstered seat with flexible pelvic support having a seat bottom with a seat pan, upholstery, and resiliently deflectable pelvic support structures retained at least partially within the central area of the seat pan. Plural resiliently deflectable fingers can project to within a left portion of the central area and plural resiliently deflectable fingers can project to within a right portion of the central area. The resiliently deflectable fingers can have different deflection resistances to permit hyper-localized control over the resilient support provided. A U-shaped rigidifying member secured to the seat pan establishes rigidified lateral and posterior portions of the seat pan. A resiliently compressible foam structure can have a U-shaped outer portion and a softer inner portion to facilitate a cradling of a seat occupant. A support and positioning member can be retained by a seat back in a fixed angular orientation relative to the seat bottom.

1. An upholstered seat with flexible pelvic support, the seat comprising: a seat bottom with a seat pan with a central area, an anterior portion, a posterior portion, and left and right portions; upholstery retained relative to the seat pan; a rigidifying member secured to the seat pan wherein the rigidifying member is U-shaped with a rear leg fixed to the posterior portion of the seat pan, a left leg fixed to the left portion of the seat pan, right leg fixed to the right portion of the seat pan and an open anterior portion whereby rigidified lateral and posterior portions of the seat pan are established; and plural resiliently deflectable fingers retained relative to the seat pan at least partially within the central area of the seat pan whereby the plural resiliently deflectable fingers provide resilient support to the seat occupant wherein at least one resiliently deflectable finger projects to within a left portion of the central area of the seat pan and at least one resiliently deflectable finger projects to within a right portion of the central area of the seat pan, wherein the seat pan has a substantially rigid, longitudinally disposed central support member, and wherein the resiliently deflectable fingers project laterally outboard from the central support member.
