  • Patent number: 5167432
    Abstract: Safety bumpers provide flexible strips for making contact inside a hollow space in a foamed body. It is suggested to carry out the making of contact by way of a closed switching strip which is mounted in a hollow space bordered by a frame preferably designed as a U-profile. An elastic pressure strip having webs extending transversely with respect to the switching strip is assigned to this switching strip. As a result, making of contact is ensured in the case of an arrangement which is not susceptible to pollution and humidity influences and which also permits a pre-assembling.
