Problems solved by technology

Such assemblies comprising a hook-and-loop system for fastening the cover are more reliable than those described in US 2003 / 0162008, but they are also very expensive, in particular requiring the hooks to cover substantially the entire bottom in order for this fastening to be sufficient Resistance to pull out
In particular, these hooks are part of elements with hooks placed at the bottom of the groove, the elements with hooks are aligned continuously, ie end-to-end, making the assembly expensive to manufacture since said elements with hooks are very expensive

Embodiment Construction

[0067] In the figure, specifically in figure 1 , shows a perspective view of the plastic sealing element with hooks according to the third solution of the present invention, which can be implemented in the first solution and / or the second solution of the present invention. The element 1 is designed to be placed in a mold to form, by molding, a molded article made of a molding material, in particular foam, more particularly thermoplastic foam. When the foam is poured into the mould, the foam contacts the molding element in liquid form and is then fastened to the molding element by coagulation. When the foam is poured into the mould, the goal is to protect the hooks so that the foam does not pass under the hooks contaminating them, because once the foam is under the hooks they become useless and can no longer cooperate with the loops And perform its hooking and hook-to-loop fastening functions.

[0068] The plastic-encapsulated component 1 comprises a plate 2 with a rectangula...

Abstract

The invention relates to an assembly comprising a molded object and a covering that covers the molded object. A longitudinal groove is formed in the molded object while being open toward the outside. Two hook elements comprise hooks being overmolded onto the molded object so as to form at least part of the base of the groove, the hooks penetrating into openings of loops from the covering so as to be hooked thereon and ensure the attachment of the covering onto the molded object, wherein said assembly is provided with at least two overmolded hook elements partially forming the base of the trench while being placed, one after the other, in the longitudinal direction, both elements being separated from each other by an intermediate area in which there is no hook element. Said assembly is moreover provided with a means for preventing the covering from rising to the top of the trench.

Description

technical field [0001] The invention relates to an assembly comprising a molded article, in particular a motor vehicle seat cushion, at least two elements with hooks molded over the molded article, and a cover at least partially covering the molded article, said cover via the hook-to-loop ( hook-and-loop) or hook-to-hook self-fastener or "touch fastener" device for fastening to a molded article, the hooks coming from a molded element with hooks and coming from the cover The loops or hooks cooperate to achieve fastening. Background technique [0002] Document US 2003 / 0162008 discloses an assembly comprising a molded article having an outer surface and a casing covering the outer surface, on which a groove or groove is formed, while said groove or groove has two opposite sides , the two sides intersect to form the bottom of the groove, the molded component has two claws placed at the bottom of the groove and a wire fixed to the housing, the wire is inserted into the groove an...
