Abstract: A modular helmet system comprises a helmet and a chin bar detachably mountable to the helmet. The helmet comprises two receiving-brackets. The chin bar may be inserted into the receiving-brackets of the helmet with its two ends in front in a substantially straight line, wherein the chin bar is lockable in the receiving-brackets in an end position. Each of the two receiving-brackets comprises two insertion flanks which extend towards each other along the direction of insertion at an acute centering angle, wherein the insertion flanks are configured to center the chin bar in the vertical direction when being inserted and to form a stop for the chin bar in the end position of the chin bar.

Abstract: A helmet comprises a shock-absorbing helmet body, which has at least one ventilation opening, and a connection structure that is embedded in the helmet body. A bridge section of the connection structure passes through the at least one ventilation opening and has a connection web and a fiber arrangement that is formed separately from the connection web and that extends along the connection web.

Abstract: A sound insulation element for the wall of a vehicle body between the passenger compartment and the engine compartment has a front side facing the passenger compartment formed by the outer side of A plastic carrier layer, and a rear side which rests against the front wall formed by the outer side of a sound-absorbing layer. At least one holding-down projection projects from the plastic carrier layer at and/or offset from the edge of the hole of the carrier layer on the inner side of the plastic carrier layer facing away from the outer side of the plastic carrier layer facing the sound-absorbing layer, which is embedded in the sound-absorbing material of the sound-absorbing layer and whose free ends facing away from the plastic carrier layer are substantially aligned with the outer side of the sound-absorbing layer facing away from the plastic carrier layer.

Abstract: The apparatus for fastening a vehicle component in and/or on a vehicle has a sound insulation element with a carrier layer and a sound absorbing layer. An anchoring recess is formed in the carrier layer and has an insertion opening in a first side of the carrier layer, which insertion opening is adjoined by a receiving space which is delimited by the plastic material of the carrier layer and is defined by a closed circumferential inner side and a closed bottom surface. An anchoring element is further provided. The anchoring recess has a constriction area formed on the circumferential inner side and at least partially narrowing the receiving space, with a widened widening area adjoining in the direction of the bottom surface. The anchoring element has an anchoring shoulder for engaging behind the constriction area when the anchoring element is received by the anchoring recess.

Abstract: Apparatus for sound insulation of a machine has a sleeve which has a sound-absorbing composite material wall with a plastic carrier layer. The composite material wall has two edge regions which lie against and/or above one another and each have a boundary edge which can be connected by at least one plug-in connection arrangement. The at least one plug-in connection arrangement has a plug-in tab arranged in one first edge region of the composite material wall and a receiving element which is arranged in the other second edge region of the composite material wall and into which the plug-in tab can be plugged. The plug-in tab has a web which has an end connected to the plastic carrier layer and an end section facing away from this end and having an insertion end and an upper side and an underside with at least one locking recess.
