Embodiment Construction

[0035] Figure 1 shows a part of a mold interior 10 for foam molding a seat cushion. Figure 1 only shows the inner part of the mould, the dashed line 12 represents the outer contour of the mould. The illustrated portion of the mold 10 includes several forming ribs or ridges 14 extending upwardly from the bottom of the mold for forming grooves in the foamed seat cushion. The ridges 14 are provided in a particular arrangement given by the design of the seat cushion and the need to attach the seat upholstery to the seat cushion. In the illustrated embodiment, the ridges are configured to form two longitudinally extending grooves and four transverse grooves extending between the two longitudinal grooves.

[0036] According to the invention, the seat sensor 16 (partially shown) comprises several flexible sensor strips 18 which must be associated with the seat cushion. This coupling is achieved by placing the seat sensor in the mold prior to foam molding of the seat cushion. The s...

Abstract

A method for fitting a sensor onto a seat cushion is disclosed, which is specifically suitable for the assembly of a seat sensor onto a seat cushion, wherein the seat cushion comprises a seating surface having a central region, said central region of said seating surface being at least partially delimited by a groove extending from said seating surface into said seat cushion, and wherein said sensor comprises a first sensor portion to be arranged at least partially at a periphery of said central region. The method comprises the steps of providing a mould (10) for foaming said seat cushion, said mould comprising at least one ridge (14) designed for forming said groove into said seating surface of said seat cushion; arranging said first sensor portion (18) in said mould on said at least one ridge (14), and foaming said seat cushion, thereby integrating at least part of said first sensor (18) portion into said seat cushion.

Description

technical field [0001] The invention relates to a method for fitting a seat sensor into a seat cushion. Background technique [0002] Seats for motor vehicles generally comprise foamed seat cushions, for example made of polyurethane foam, which are placed on a solid support structure and covered by a seat upholstery made of textile material or leather. Such seat pads include one or more grooves extending from the upper seat surface of the seat pad into the seat pad. Seat pads typically include, for example, two longitudinally extending grooves separating the central seat surface from the side back cushions, and one or more transverse grooves extending between opposing longitudinal grooves. [0003] Grooves are often used as tuck channels for attaching seat upholstery to the seat cushion. For this, the metal wire is embedded in the seat pad so as to extend along the groove and is partially exposed inside the groove. The seat upholstery may then be attached to the exposed p...
