Definitions
- the invention relates to a protective helmet with a connecting device for releasable attachment a tapeless respirator as described in the preamble of claim 1 is:
- DE-A1-40 37 034 describes a combination of a protective helmet with a breathing mask known in which the connection of the protective helmet with the respiratory mask via two detachable Coupling parts are done.
- the helmet-side coupling part is on a pivot axis on Carried frame or in the inner helmet of the protective helmet so that it is between the outer shell the protective helmet and the inner helmet or the support frame.
- On the a mushroom-shaped bolt is arranged on the helmet-side coupling part.
- the further coupling part the respirator has a buttonhole-like opening with a large diameter and a narrow, narrow, elongated extension.
- the clutch part on the helmet side can be swung out of its rest position, so that the coupling part of the respirator can be hung with the opening in the mushroom-shaped bolt. Thereupon will the coupling part on the helmet side is pivoted in the direction of its rest position around the respiratory mask to approach the face of the fireman and an airtight seat of the Reaching face mask on the firefighter's face.
- the disadvantage here is that if the coupling part is stored for a longer period inside the protective helmet shell of the coupling part is deformed such that a provision when swiveling the coupling part out of the Rest position is no longer present, so that when connecting the respirator to the Hard hat can be difficult due to the deformation of the coupling part.
- WO-A-95/09675 published on April 13, 1995
- a protective helmet with a connecting device for releasable attachment of a tapeless respirator known.
- This has two connecting elements on, each in the area of either of the user's ears facing flank area of the safety helmet and in one of the two side areas of the Respirator is attached.

- a protective helmet for the detachable attachment of a respirator with a connecting device known - according to DE-C3-26 40 701 -, in which both locking elements of the connecting device, which are releasably engageable with each other, within the perimeter of the protective helmet are arranged.
- This connection device is, for example from a locking bell, which has a holding element in a recess of the protective helmet is held, into which a locking element fastened to the respiratory mask can snap, whereby by means of appropriate adjustment, a sufficient pre-tension between the respirator mask and the face of the user and the support of the counterforce via the protective helmet is achievable.
- the disadvantage here is that the determination or adjustment of the contact pressure and the loosening of the fastening device by the bearing device penetrating the protective helmet the connecting device and accordingly the protective helmet with relative large openings and recesses must be provided.
- Another known hard hat - according to EP-B 1-0 105 813 - has a rigid cap and an inner hood made of supple transverse bands, the side parts of which are in the middle Longitudinal plane of the protective helmet symmetrical and lying approximately at the level of the user's ears Points converge, with the hard hat on the removable respirator is articulated by at least one side fastening arm of adjustable length.
- the cap of the protective helmet is on the outside of each of its sides at the level of the user's ears with hooking notches or slots for attaching two side mounting arms Mistake. These are connected to the respirator mask on both sides.
- Everyone who lateral mounting arms has two telescopic elements, which are supported by resilient elements connected and biased so that they try to penetrate each other.
- a hook cooperating with the associated hooking notch of the calotte is pivotally mounted on the rear telescopic member of the mounting arm.
- To the front telescopic element of the mounting arm and on an extension of the hook sling means are provided through which the two elements temporarily in the extended position are lockable. Unlocking means are also provided for these slings, by supporting the fastening arms on the outer surface of the protective helmet when putting on the respirator can be triggered. With such a protective helmet and one with this connected respirator could not be sufficient in all cases Safety for the user of such a combination of protective helmet and respirator can be achieved.
