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 pi

Example

[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 a central flexible tongue piece 112c with a snap hook for fastening to a corresponding female part in the form of a fixation slot which is arranged in the helmet.

[0042] The receiving piece 111 of the helmet piece contains an elastically resilient tongue 113 with a circular-arc flange 117 projecting forward (to the left in FIG. 4d). The receiving piece 111 also contains a semicircular flange 114, projecting radially inward and arranged around the tongue 113, a lower circular-arc edge 115, and a first stop piece 116 projecting forward. Furthermore, the helmet piece 101 ...

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 ...
