Benefits of technology

[0014] One purpose of the present invention is therefore to provide an improved arrangement for fastening of a hearing protection to a helmet.
[0015] Another purpose is to provide an arrangement which leads to a more secure retention of the hearing protection in a resting position rotated upward outside the helmet.
[0016] Furthermore, one purpose is to provide an arrangement which reduces the risk of damage to the helmet and the arrangement.

Problems solved by technology

One problem with the above described known arrangement, however, is an inability to maintain the cap holder piece in the resting position.
This is often perceived as an annoyance by the user.
This results in relatively large forces, for example, at the fastening of the helmet piece in the helmet, which are liable to damage the helmet and / or the helmet piece of the arrangement.
Due to the lower shape stability of PE, some of the problems connected with the above described known arrangement are even more serious when using protective helmets made of PE.

Embodiment Construction

[0038] The following describes two sample embodiments of the invention with regard to FIGS. 3-7. In these drawings, the embodiment shown in FIG. 6 differs from the embodiment shown in FIG. 3-5 and 7 merely in that the helmet piece of the arrangement is shaped differently in order to fit different helmets whose slots for attachment of the hearing protection have a different geometrical configuration.

[0039] The arrangements according to the invention, shown in FIG. 3-7, like the known arrangement shown in FIG. 1a-c, contain a helmet piece 101 and a cap holder piece 102.

[0040]FIG. 4a-c shows only the helmet piece 101 for a first embodiment of the invention. FIG. 5 shows on magnified scale only a receiving piece 111 of the helmet piece 101.

[0041] The helmet piece 101 contains a receiving piece 111 and an elastic fixation tongue 112, projecting downward from the receiving piece. The fixation tongue 112 is configured as a male part and it contains two outer tongue pieces 112a, 112b and...

Abstract

Arrangement for securing a hearing protector to a helmet, which arrangement comprises a cap holder piece (102) and a helmet piece (101). The cap holder piece contains a rotary plate (103), a bistable element (104) and a cap holder element (105), which is secured by means of the bistable element to the rotary plate to allow a hearing protection, secured to the cap holder element, to take up a tilted out and a tilted in position relative to the rotary plate. The helmet piece comprises means (112, 112′) of attachment to a helmet and a receiving piece (111), in which the rotary plate is secured, able to turn about an axis of rotation, which receiving piece includes a resilient tongue (113) essentially parallel to the axis of rotation and a first stop piece (116) which, under the action of the resilient tongue and in cooperation with a second stop piece (132) arranged on the rotary plate, releasably maintains the rotary plate in a first rotational position relative to the receiving piece. To prevent the cap holder piece from accidentally leaving the first rotational position, the arrangement includes a first projection (119) extending from the receiving piece essentially parallel to the axis of rotation, which in the first rotational position limits the motion of the rotary plate toward the resilient tongue by thrusting against the cap holder piece.

Description

FIELD OF THE INVENTION [0001] The invention concerns an arrangement for securing a hearing protector to a helmet according to the preamble of patent claim 1. The invention also concerns a helmet with such an arrangement. [0002] 1. Background [0003] Nowadays, thanks to laws and regulations, many work situations require the employer to provide both a protective helmet and hearing protection to guard against various risks to the personnel during their work. One example is felling of trees with a chain saw. Most of the manufacturers of protective helmets have therefore adapted the configuration of the helmet as a standard model so that hearing protection can be attached to the helmet in that there is a slot or the like in the edge of the helmet on either side above the position of the ear. The hearing protection for the helmet is then provided with a helmet part that can be attached to the helmet in the slot, for example, by a snap fastener. [0004] The hearing protection is worn during ...
