The elastomeric element 103 comprises a material that is fixed in shape but elastically deformable, in particular a plastic that is fixed in shape and elastically deformable, such as, for example, a polyurethane material, in particular, seloma, or a rubber material, in particular, a sponge rubber. The elastomeric element 102 is arranged on the second leg 106 of the fastening unit 100, wherein the elastomeric element 103 is arranged on the end region of the second leg 106 that is away from the fastening region 107. Here, the elastomeric element 103 is arranged on one side of the second leg 106 toward the first housing funnel 29, in particular toward the first housing funnel 29, which extends perpendicularly to the surface 33 of the patient accommodation region. The elastomeric element 103 is bonded to the second leg 106 here. In addition, other fastening types that are considered reasonable by those skilled in the art between the elastomeric element 103 of the fastening unit 100 and the second leg 106 are feasible at any time. The fastening unit 100 is arranged on the first housing funnel 29 in this case, so that the elastomeric element 103 rests on the first housing funnel 29, in particular on the housing side 32 of the first housing funnel 29 extending perpendicularly to the surface 33 surrounding the patient accommodation area. In addition, the fastening unit 100 is supported on the first housing funnel 29, in particular on the housing side 32 of the first housing funnel 29 extending perpendicularly to the surface 33 surrounding the patient accommodation area, via the elastomeric element 103.

[0053] The fastening unit 100 has two opposite end regions 111, 112, wherein the locking element 102 is arranged on the first end region 111 and the elastomeric element 103 is arranged on the second end region 112 opposite the first end region 111. Here, the locking element 102 is arranged on the end region of the first leg 105 facing away from the second leg 106, and the elastomeric element 103 is arranged on the end region of the second leg 106 facing away from the first leg 105. The fastening region 107 of the fastening unit 100 includes a rotation axis 113 for the locking movement of the locking element 102, wherein the locking movement includes a rotational movement. The fastening region 107 includes a cylindrical segment-shaped region, wherein the cylindrical segment-shaped region has a longitudinal axis parallel to the rotation axis 113.

[0054] In order to stabilize the fastening region 107 during the locking movement, the fastening unit 100 has a D-shaped element 114 arranged in the fastening region 107 of the fastening unit 100.

Here, the D-shaped element 114 is arranged in the fastening region 107 such that the recess 115 and / or the transverse direction 116 of the D-shaped element 114 is oriented perpendicularly to the housing side 32 of the housing funnel 29 , in particular to the region of the housing side 32 provided for fastening to the fastening unit 100 .

[0055] For the locking movement, the first leg 105 is deflected together with the locking element 102 about the rotation axis 113. The direction of rotation here is in the direction of the elastomeric element 103. Due to the rotation area with the D-shaped element 114, the second leg 106 is also rotated together with the elastomeric element 103 in the rotation direction. In this case, the elastomeric element 103 is elastically compressed and / or deformed. The locking force and / or the maximum deflection are defined here by the elastomeric element 103, in particular the material selection of the elastomeric element 103.

[0056] In order to stabilize the two legs 105, 106 during the locking movement and / or during the locking connection with the housing 29 surrounding the patient receiving area 12, the fastening unit 100 has at least one reinforcement element 117. The reinforcement element 117 determines the spacing between the locking element 102 and the elastomeric element 103 or the spacing between the two legs 105, 106. In the present embodiment, the fastening unit 100 has two reinforcement elements 117 arranged parallel to each other. Each reinforcement element 117 is designed as a reinforcement strut. In principle, other configurations of the reinforcement element 117 that appear reasonable to a person skilled in the art are conceivable at any time.
