HEAD RESTRAINT

Abstract

A head restraint for a vehicle seat for a vehicle for at least one person. The head restraint has a front side facing the person sitting on the vehicle seat and a rear side arranged opposite to the front of the head restraint. The head restraint has a head box and at least one foam body. The foam body is applied around at least part of the head box and covers at least a part of the head box arranged in the direction of the front side of the head restraint and also covers at least part of the part of the head box arranged in the direction of the rear side of the head restraint. The foam body is designed such that the part of the foam body which covers the rear side of the head restraint can form a resonance volume.

Description

[0044] FIG. 1 shows a head restraint 1 according to the invention, wherein only the head box 2 and two frame rods 3 are shown in FIG. 1. FIG. 1 shows the side that faces in the direction of the person on the vehicle seat 1 when, for example, a covering (not shown) and a perforated, one-piece foam body 7 (not shown) have been removed. In this exemplary embodiment, this foam body 7 is formed in such a way that it forms a cavity in its interior.

[0045] The side of the head restraint 1 shown in FIG. 1 is thus the front side. FIG. 2 shows the head restraint 1 from FIG. 1 in a view which is arranged opposite to the view from FIG. 1, that is to say the head restraint 1 is shown in FIG. 2 as the rear side.

[0046] The head box 2 is formed in one piece and has two areas, each of which enables a loudspeaker 5 to be accommodated. These two areas are designed as loudspeaker recesses 4.

[0047] A loudspeaker 5 in the form of two individual loudspeakers 5a, 5b for the head restraint 1 is shown in FIG. 3. Furthermore, FIG. 3 shows a loudspeaker cable 6, using which the respective individual loudspeaker 5a, 5b can be controlled.

[0048] The loudspeaker recesses 4 in the head box 2 according to FIGS. 1 and 2 are designed in such a way that the integral head box 2 has at least one opening at these points, so that sound waves from the respective loudspeaker 5 in the loudspeaker recess 4 can be directly incident on the perforated area 7a of the foam body 7 and can subsequently be incident on the covering (not shown). In FIG. 1, six openings are shown which are associated with a respective loudspeaker recess 4 in the head box 2. That is to say, each loudspeaker recess 4 has six openings. The loudspeakers 5 are screwed into the respective loudspeaker recess 4, wherein this is not shown in the figures.

[0049] FIG. 4 shows a head restraint 1 according to FIGS. 1 and 2, which has, inter alia, a head box 2 and furthermore two frame rods 3. According to FIG. 4, an individual loudspeaker 5a, 5b according to FIG. 3 is inserted into each of the two loudspeaker recesses 4 and accordingly screwed to the head box 2.

[0050] In the direction of the front of the head restraint 1, the foam body 7 is indicated according to FIG. 4, wherein the head box 2 is arranged between loudspeaker 5 and foam body 7 in relation to the front side according to FIG. 4. In relation to the rear side, the foam body 7 conceals the two frame rods 3 and the loudspeaker 5. The rear side of the head restraint 1 is thus also suitably covered or enveloped by the foam body 2. The components are thus located in the cavity of the foam body 7 that forms when the foam body 7 is pulled over the components. According to FIG. 4, the foam body 7 is designed to be perforated in the front area in the direction of the front side. A perforated area 7a is thus formed in this area. The components of the head restraint 1 shown in FIG. 4 are only indicated or can be indicated due to the schematic representation.

[0051] The foam body 7 is thus applied to the head box 2 in FIG. 4 in such a way that it envelops the head box 2, the two frame rods 3 in the area of the head box 2, and the loudspeaker 5 in a suitable manner

[0052] According to the invention, this head restraint 1 can be covered by a covering (not shown)

[0053] When sound 9, that is to say, a tone or a sound wave, comes from a loudspeaker 5, it is conducted through the openings of the loudspeaker troughs 4, subsequently through the perforated area 7a of the sound body 7, that is to say, for example, a through opening like a hole, and the covering (not shown) to the person on the vehicle seat 1. The sound 9 is thus transmitted in the direction of the front side.

[0054] The area of the foam body 7 which faces in the direction of the rear side of the head restraint 1 forms the resonance volume between loudspeaker 5 and foam body 7 itself. In this resonance volume of the foam body 7, dissipation of the rear sound takes place, which is generated by the loudspeaker 5 in the direction of the rear side of the head restraint 1. The foam body 7 itself thus acts in its area on the rear side as a resonance body, wherein no further cover in the form of, for example, a further cover cap or the like is necessary to generate such an effect.
