Abstract
In a particle foam component with an embedded fastening element consisting of a thermoplastic or elastomeric plastic, the fastening element is surrounded at least in some sections by a wrapping consisting of a first particle foam of a first plastic. A bonding in substance and/or a positive-locking connection is brought about in a first contact surface between the fastening element and the wrapping. The wrapping is surrounded at least in some sections by a molded part made of a particle foam of a second plastic, and a bonding in substance is brought about in a second contact surface between the wrapping and the molded part.
Claims16
A particle foam component, comprising:
- an embedded fastening element, wherein the fastening element is surrounded at least in some sections by a wrapping comprising a first particle foam of a first plastic, wherein at least the wrapping is surrounded at least in some sections by a molded part comprising a second particle foam of a second plastic, the fastening element comprising a thermoplastic or elastomeric plastic, wherein a bonding in substance or a positive-locking connection and a bonding in substance is provided in a first contact surface between the fastening element and the wrapping, and a bonding in substance is provided in a second contact surface between the wrapping and the molded part.
A method for producing a particle foam component, the method comprising:
- forming an embedded fastening device from a fastening element made of a thermoplastic or elastomeric plastic and a wrapping, which at least partially surrounds the fastening element and said wrapping is made of a first particle foam of a first plastic, and a bonding in substance or a positive-locking connection and a bonding in substance is brought about in a first contact surface between the fastening element and the wrapping, wherein the fastening element provided with the wrapping is subsequently placed into a mold and at least the wrapping is surrounded with a molded part made of a second particle foam of a second plastic, and a bonding in substance is brought about in a second contact surface between the wrapping and the molded part.
A fastening device to be inserted into a particle foam component, the fastening device comprising:
- a fastening element comprising plastic;
- and
- a wrapping, which surrounds the fastening element at least in some sections and said wrapping is made of a first particle foam of a first plastic, the fastening element comprising a thermoplastic or elastomeric plastic, wherein a bonding in substance or a positive-locking connection and a bonding in substance is provided in a first contact surface between the fastening element and the wrapping.
