Description

[0001] Headband with swivel axis

[0002] The invention relates to a headband for placing on the head of a user, wherein at least one receptacle for attaching an ear cup is provided at the end of the headband, wherein the receptacle ensures that the ear cup can be tilted about a tilting axis_L, wherein the headband has a central axis and a U-shaped base_G extending in a direction_U of the central axis.

[0003] The invention also relates to a system consisting of a headband according to one of the preceding claims and a protective helmet for placing on the head of a user, wherein the protective helmet has a protective helmet edge and can be placed above the headband.

[0004] The invention also relates to a system consisting of a headband according to one of the preceding claims and at least one ear cup attached to the mount with an upper housing edge.

[0005] A headband with a tilting axis is already known from US 2021 0186140 A1, embodiment shown in Fig. 2. Alternatively, an ear cup holder on the helmet side, which has a pivoting axis, is described according to embodiment Fig. 2.

[0006] A corresponding embodiment is known from WO 2022-112757A1 according to embodiment Fig. 1 and embodiment Fig. 9 in conjunction with Fig. 15.

[0007] The invention is based on the objective of designing and arranging a headband in such a way as to ensure a wider range of applications and improved comfort.

[0008] The problem is solved according to the invention by a) the headband having a pivot bearing with a pivot axis_Q between a headband center and the receptacle, wherein the pivot axis_Q is i) oriented perpendicular to or at least transverse to the tilting axis_L and / or ii) oriented parallel to a principal plane_E of the headband, wherein the principal plane E is spanned by the central axis, or b) the receptacle for attaching an earpiece has two ball or cross joints, wherein the receptacle also has telescopic means by means of which a distance_k between the respective ball joint and the headband can be changed. This ensures that an earpiece attached there can perform a pivoting movement about a pivot axis_Q in addition to the tilting movement. This allows, firstly, the position of the earpiece on the ear to be adjusted by pivoting it about a pivot angle α, and secondly, the relative position of the earpiece to a helmet or similar device to be adjusted.whose edge is adjusted. The tilting axis_L is positioned at the lower end of the respective recording.

[0009] It can also be advantageous if the headband has a central axis and a U-shaped base_G extending in a directionJJ of the central axis, wherein the pivot axis_Q with respect to the direction_U has a distance_a to the tilt axis_L, with 30 mm <= a <= 70 mm or 40 mm <= a <= 60 mm or 45 mm <= a <= 55 mm.

[0010] The contact pressure of an ear cup can be varied by adjusting the distance_a between the pivot axis_Q and the tilt axis_L. Pivoting the headband by a pivot angle_a causes an offset_V relative to the main plane_E of the headband, which is defined by the central axis. Spreading the headband results in a torque, or torsion, of the headband about its central axis or about a tangential torsion axis_T perpendicular to the pivot axis_Q. The section modulus of the headband about the torsion axis_T is less than the section modulus about a main bending axis_H, which is perpendicular to both the pivot axis_Q and the torsion axis_T. This torsion counteracts the contact pressure of the headband against the head on the proximal side of the ear cup. Pivoting backward reduces the contact pressure behind the ear, while pivoting forward reduces the contact pressure in front of the ear.The fact that the pivot axis_Q or the pivot bearing is located above the upper edge of the housing also has an advantageous effect. It is advantageous for the pivot bearing to be positioned as close as possible to the upper edge of the housing.

[0011] Furthermore, it can be advantageous if the respective ball or cross joint of the respective mount can be positioned at different distances_k1, _k2 using the telescopic means. This also allows the respective ear cups to be pivoted around an axis parallel to the pivot axis_Q. The headband is designed without translation bearings in the U direction, thus it is free of translation bearings. This makes the headband very easy to integrate into a helmet pad.

[0012] It can also be advantageous if the pivot axis_Q is positioned in relation to direction_U in the area of ​​one end of the headband or at the end of the headband pivoting part, or if the pivot axis_Q is positioned at the height of the tilt axis_L, i.e., at the end of the respective mount with distance_a = 0. Both ensure the adaptation of the relative position of the ear cup to the protective helmet or to the ear.

[0013] Furthermore, it can be advantageous if the headband is designed in two parts and comprises a headband main part and at least one first headband pivot part on which the receptacle is mounted (directly or indirectly), wherein the headband pivot part is coupled to the headband main part via the pivot bearing. The headband pivot part is mounted directly or indirectly on which the receptacle is mounted.

[0014] It can also be advantageous to include a translational bearing, where the translational bearing and the pivot bearing are superimposed. The translational bearing can compensate for an offset_V to the main plane_E of the headband, particularly when the relative position between the ear and the auricle necessitates it.

[0015] The problem is also solved by a system consisting of a headband and a protective helmet for placing on the user's head, wherein the protective helmet has a protective edge and can be positioned above the headband, with the pivot bearing being located above the protective helmet edge when the helmet is in place. This allows the position of the ear cup to be easily adjusted to the protective helmet edge.

[0016] The problem is also solved by a system consisting of a headband and at least one ear cup attached to the mount, with an upper housing edge, the swivel bearing being located above the upper housing edge. This allows the position of the ear cup to be easily adjusted to the edge of the protective helmet.

[0017] A similar effect is achieved by the fact that the pivot bearing is positioned above the edge of the helmet when it is in place. Advantageously, the pivot bearing can be positioned as close as possible to the edge of the helmet when it is in place.

[0018] Further advantages and details of the invention are explained in the claims and the description and illustrated in the figures.

[0024] Figure 6a Headband with telescopic means and ball joint;

[0025] Figure 6b Headband with telescopic means and ball joint. A headband 1 shown in Figure 1 has a headband main part 1a, a first headband pivot part 1b, and a second headband pivot part 1c. The respective headband pivot part 1b, 1c is coupled to the headband main part 1a via a pivot bearing 1.3, 1.5. A receptacle 2.1, 2.2 is provided on the respective headband pivot part 1b, 1c, which has two retaining brackets 1.7a, 1.7b. For clarity, the second receptacle 2.2 is not shown in Figures 1, 2, and 3. The pivot bearing 1.3 has a pivot axis Q that runs perpendicular to a central axis 1.4 of the headband 1 or the headband main part 1a. The headband main part 1a extends along the central axis 1.4 in a circumferential direction U. The curved central axis 1.4 spans a principal plane E, to which the pivot axis Q runs parallel.

[0026] At its end, each receptacle 2.1 has a tilting axis L, about which an ear cup can be tilted on the receptacle 2.1 or the retaining brackets 1.7a, 1.7b. The pivot bearing 1.3 is located at a distance a from the tilting axis L. Both the headband main part 1a and the two headband pivot parts 1b, 1c are made of flat material and have a band-shaped basic form G.

[0027] According to the embodiment shown in Figure 2, the first headband pivot part 1b is pivoted relative to the headband main part 1a about the pivot axis Q by approximately 8 to 10 degrees. This pivoting results in an offset V relative to the main plane E, which is defined by the curved central axis 1.4, starting from the original position of the mount 2.1 according to Figure 1.

[0028] According to the embodiment shown in Figure 3, a translation bearing 4.1 is superimposed on the pivot bearing 1.3, allowing the headband pivoting part 1b to be moved translationally forwards and backwards without affecting the pivot position, thus compensating for the offset V as shown in Figure 3. The headband pivoting part 1b, together with the first mounting, remains pivoted by an angle α of approximately 8 to 10 degrees. According to the embodiment shown in Figure 4, a headband 1 with arranged ear cups 3.1, 3.2 is placed on a user's head 1.1. A protective helmet 5 with a protective pad 5.2 is mounted on the headband 1. The ear cups 3.1, 3.2 are tiltably mounted to the respective mountings 2.1, 2.2 and the retaining brackets 1.7a, 1.7b. The two pivot bearings 1.3, 1.5 are also shown. The pivot bearing 1.3 has a distance a1 with respect to a helmet edge 5.1. With respect to an upper housing edge 3a of the respective ear cup 3.2, the pivot bearing 1.3 has a distance a2.Thus, the respective pivot bearing 1.3, 1.5 is arranged both above the helmet edge 5.1 and above the upper housing edge 3a. In the area of ​​the headband center 1.2 at the upper point, the headband 1 is positioned sandwich-like between the head 1 and the helmet pad 5.2. The ear cup 3.1 is equipped with a microphone 3.3, which can be placed in the mouth area.

[0029] According to Figure 5, the pivot angle α is 90 degrees. The offset V is at its maximum. This is accompanied by a torsional moment about a torsion axis T, which is arranged perpendicular to the pivot axis Q and tangential to the central axis 1.4. Due to this torsion, the contact pressure of an ear cup decreases depending on the distance to the pivot axis Q and the distance to the pivot bearing 1.3 between the headband main part 1a and the headband pivot part 1b, 1c. The main bending axis H, as the central axis for spreading the headband, is aligned perpendicular to the pivot axis Q and perpendicular to the torsion axis T.

[0030] According to the embodiments shown in Figures 6a and 6b, the respective receptacle 2.1, 2.2 of the headband 1 has two retaining brackets 1.7a, 1.7b, each of which is provided with a ball joint 2.3a, 2.3b at its respective end 1.6. Furthermore, the headband 1 and the retaining brackets 1.7a, 1.7b have telescopic means 2.4a, 2.4b. The telescopic means 2.4a, 2.4b serve to adjust a distance k between the ball joints 2.3a, 2.3b and the headband 1.

[0031] According to the embodiment shown in Figure 6a, a pair of sockets and, according to the embodiment shown in Figure 6b, a pair of balls are provided. Strictly speaking, they only form the first part of a ball joint. The respective ear cup (not shown here) has a corresponding second part, i.e., a pair of balls or a pair of sockets, so that part 1 and part 2 of the ball joint interlock. Thus, the ear cup is mounted in a three-way configuration. All three axes of rotation are free.

[0032] In addition, the respective retaining bracket 1, 7a, 1, 7b of the

[0033] Figures 2.1 and 2.2 show the telescopic means 2.4a and 2.4b, which allow for changing the length of the respective retaining bracket 1, 2.7a, and 2.7b, or for changing the distance k. According to the embodiment shown in Figure 6a, the distance k of both ball joints 2.3a and 2.3b to the head bracket 1 is approximately the same. This would be the previously known standard case.

[0034] However, different distances k can be selected by using the telescopic elements 2.4a, 2.4b. According to the embodiment shown in Figure 6b, the distance k1 of the left ball joint 2.3a is greater than the distance k, and the distance k2 of the right ball joint 2.3b is less than the distance k. The superposition of the telescopic elements 2.4a, 2.4b and the ball joints 2.3a, 2.3b results in a pivot bearing 1 .3 with the pivot axis Q, which enables a pivoting of an earpiece about the pivot axis Q, which is mounted in the receptacle 2.1 via the ball joints 2.3a, 2.3b (not shown here).
