Description

Bolster The present invention relates to bolsters of the type of the one having been the subject of Swiss patent NO 390488 composed of a double wall with cross section of general profile in oval whose base, of dimension reduced in thickness, is intended to serve as a support for the user's head while avoiding the breakage of the neck, a breakage that is blamed on round bolsters at the same time as the resting surface is wider.

The present invention relates to a bolster of this type, but having new characteristics intended to improve its comfort. According to the invention, the tapered part on which the neck rests has a greater flexibility than in its most raised part on which the occiput rests and this, by means of fillings of different flexibility and separated one from the other. the other by a transverse partition in flexible fabric.

The accompanying drawing represents, by way of example, two embodiments of the invention in FIG. 1 shows in perspective, with cross-section, a first form of execution; fig. 2 represents, in the same way, a second form of execution.

According to the mode of execution of FIG. 1, this bolster is composed of two concentric envelopes 1 and 2 with a cross-section in the shape of a flattened oval on one side and forming between them an intermediate space 3. The capacity delimited by the inner envelope 1 is divided into two compartments 4 and 5, by a dividing wall 6 made of flexible fabric.

Compartment 4 located in the narrowest tapered part is lined with down, half-down, or any other very supple and soft animal, plant, artificial or synthetic material, while compartment 5, on which rests the occiput is lined with a material presenting a greater resistance to pressure such as, for example, feather.

As for the intermediate space 3 located between the two casings 1 and 2, it is advantageously lined with horsehair, or any other animal, vegetable, artificial or synthetic material. In the handset thus produced, the neck and the cervical vertebrae therefore rest on a very flexible profiled surface, while the upper part of the handset yields under the weight of the occiput. The line of rest from the occiput to the cervical vertebrae is thus uniform without any cantilevered surface, which constitutes from a medical point of view a very appreciable advantage for the vertebral column.

This last advantage is even more accentuated RTI ID="0001.0266" WI="7" HE="4" LX="1908" LY="1964"> in the mode of execution of FIG. 2, according to which the lower face of this bolster is flat or substantially flat, so that its section is not in the shape of an oval, but in the shape of a half-oval with a very flattened front section, the double wall between the two envelopes 1 and 2 remaining only on the upper face.

The dividing wall 6 is then sewn onto the lower face of the envelope 1, just as On the upper face of the same envelope which is connected by sewing to the outer envelope 2, the intermediate space 3 being filled with a sheet of polypropylene fiber.

Claims (3)

CLAIM Double-walled bolster with a cross-section of generally oval profile, characterized in that its most tapered part on which the neck rests has greater flexibility than in its most raised part on which the occiput rests, and this at the means of fillings of different suppleness and separated from each other by a transverse partition made of flexible fabric. SUB-CLAIMS 1. Bolster according to claim, characterized in that its underside which rests on the mattress is flat. 2. Bolster according to claim, characterized in that its outer casing is stitched onto an inner casing with the interposition between them of a sheet of flexible fibre. 3. Bolster according to claim and sub-claim 2, characterized in that the layer of flexible fiber interposed between the two casings is made of polypropylene.
