Definitions
- the invention relates to a head protection combination of the type specified in the preamble of claim 1.
- EP 0 646 333 B1 discloses a head protection combination with two hearing protection capsules.
- the ear protection capsules are each fixed to a headband on the helmet of the head protection combination.
- the earmuffs can be pivoted outwardly away from the user's ear.
- the vertical position of the earmuffs on the headband in the longitudinal direction of the retaining clip is adjustable. In the operating position, the ear protection capsule is pressed by the headband, which is resilient, against the head of the user. With such a holder, depending on the head shape of the user, insufficient sound insulation results may result.
- the invention has for its object to provide a head protection combination of the generic type, which allows a good adaptation to the head shape of the user and can be achieved with the good sound damping properties.
- the installation of the hearing protection capsules on the head of the user in an area behind the ear can be achieved by the provided adjustable rotational position. It is achieved a good adaptation of the position of the earmuff to the respective head shape of the user.
- the axis of rotation about which the rotational position of the hearing protection capsule is adjustable can lie parallel to the vertical or include an angle with the user in upright head posture, so if the user carries the helmet in a conventional manner on the head and keeps the head upright is less than 45 °. Accordingly, adjustability is achieved about a substantially vertically oriented axis of rotation.
- a good conditioning of the hearing protection capsule can also be set in an area behind the ear.
- the hearing protection capsule is fixed to the helmet via a retaining bracket.
- the first axis of rotation extends in particular approximately parallel to the longitudinal direction of the retaining clip.
- the imaginary connecting line between the attachment of the retaining clip to the helmet and the attachment of the ear protection capsule to the headband is meant.
- the rotational position of the ear protection capsule relative to the headband is adjustable. Thereby, the function of folding down the retaining clip and the adjustment of the rotational position of the ear protection capsule on the headband can be formed spatially separated, so that sufficient space is available.
- the hearing protection capsule is fixed to the helmet via a spherical bearing.
- the spherical bearing not only the rotational position about the first axis of rotation, but also the rotational position can be adjusted about a perpendicular thereto axis of rotation.
- the position of the earmuff on the headband can be adjusted within predetermined limits forward and backward. This allows a good adjustability.
- the spherical bearing comprises a bearing plate with a spherical portion and a releasable clamping device, wherein the spherical portion of the bearing plate can be fixed via the clamping device in different positions on the headband. The clamping device can be easily released and fixed again by the operator.
- the rotational position of the ear protection capsule relative to the headband must be set only once for a user. Since the relative position between hearing protection capsule and headband is maintained via the clamping device, no renewed adjustment is necessary when working again with the head protection combination. An adjustment of the retaining bracket to the side or to the rear does not affect the position of the ear protection capsule on the headband.
- the hearing protection capsule is pivotally held on the headband about a substantially horizontally disposed pivot axis when the user is upright head posture.
- a good automatic adaptation of the position of the earmuff to the head shape of the user is achieved in this direction.
- the position of the retaining clip relative to the helmet is approximately vertical in the case of an upright head posture of the user. adjustable. This also allows a further possibility of adapting the position of the hearing protection capsule relative to the helmet to the head shape of the user.
- the fact that the position of the ear protection capsule about the axis of rotation relative to the headband and the position of the retaining bracket in the vertical direction relative to the helmet is adjustable, the different adjustment options are spatially separated, so that there is a comparatively simple structural design.
- an inner holder is arranged on the headband on the end facing away from the ear defenders capsule, wherein the position of the inner holder relative to the helmet in particular in approximately vertical head posture of the user is adjustable approximately vertical direction.
- a toothing is advantageously arranged on the inner holder, which defines different positions of the inner holder relative to the helmet.
- the toothing defines predetermined relative positions between the holding bracket and the helmet. By counting the teeth so the same height of the earmuffs can be achieved on both sides of the helmet. The toothing ensures at the same time a tight fit of the inner holder to the helmet.
- the retaining clip with the ear protection capsule opposite the helmet is arranged between an operating position in which the ear protection capsule is arranged on the user's head and a rest position in which the ear protection capsule is arranged laterally away from the user's head.
- a lateral distance is meant a distance from the head of the user to the outside, ie in the lateral direction of the user's head.
- the head protection combination expediently has a holding unit direction, which holds the headband in the operating position and in the rest position. As a result, the earmuff in the rest position does not have to be held by the user.
- the holding device is arranged in the inner holder. This results in a compact design. In an adjustment of the vertical position of the retaining clip relative to the helmet, the inner holder may remain closed, so that unintentional disassembly of the holding device is avoided.
- the holding device comprises a spring which is designed as an open spring ring. This spring has a simple structure and can be easily assembled and disassembled. The spring ring can be made comparatively large, so that the assembly is simplified.
- the headband is adjustable from the rest position to a non-operational position, wherein the ear defender capsule is arranged in the inoperative position in the rear region of the helmet at a distance from the helmet.
- the rear area of the helmet is the area arranged in the region of the back of the head of a user. Because the hearing protection capsule is arranged in the inoperative position at a distance from the helmet, contamination of the hearing protection capsule is avoided by resting on the usually heavily soiled helmet.
- the headband for the inoperative position is adjustably held about a second axis of rotation on the helmet, wherein the second axis of rotation in upright head posture of the user includes an angle of more than 45 ° with the vertical.
- the headband is fixed to the helmet via a mount, and the mount is adjustably fixed to the helmet relative to the helmet about the second axis of rotation.
- the holder has a first toothing, which cooperates with at least one latching nose and determines the detent positions of the holder relative to the helmet.
- the first toothing is formed on a base plate of the holder and the base plate has a second toothing, which cooperates with the inner holder. This achieves a compact construction with a small number of individual parts.
- the headband is dimensionally stable.
- the headgear assembly comprises a face shield which can be placed in an operative position and in an inoperative position on the helmet.
- the face shield is located in the inoperative position outside the field of view of the user.
- a face shield with a wire net or with a plastic disc It is known to provide a face shield with a wire net or with a plastic disc.
- the plastic disc or wire mesh is bent in known face shields in a holder.
- the bracket prevents bending back. It has shown, that the bending of a flat plastic disc deteriorates the optical properties.
- the face shield has a face shield made of preformed plastic.
- a face shield made of preformed plastic has good optical properties. Even with partial damage of the holder in which the face shield is arranged, the face shield does not have a tendency to bend back, so to a flat disc.
- the formation of the face shield from preformed plastic represents an independent inventive idea.
