Description

Motor vehicle seating arrangement The invention relates to a motor vehicle seating arrangement with the features of the preamble of patent claim 1, according to document US 2016 / 172797 A1. Another type of motor vehicle seat arrangement is known as the "Travel & Comfort System," as exemplified by the motor vehicle manufacturer BMW. This system allows for the flexible and easy attachment of various accessories to a motor vehicle seat; in practice, the system has also proven its effectiveness due to its high level of ease of use and its high level of safety in the event of a collision. Other motor vehicle seating arrangements are known from documents DE 102014222672 A1, DE 102009030895 A1, DE 102015206262 A1 and DE 102019103872 A1. The invention is based on the objective of proposing a motor vehicle seat arrangement that is also suitable for supporting relatively heavy electronic devices. This objective is achieved in a motor vehicle seating arrangement of the type mentioned at the beginning by means of the characterizing features of claim 1 of the patent. The motor vehicle seat arrangement according to the invention also allows for the simultaneous connection of several insertable parts to a motor vehicle seat, specifically from the same side of the seat. In particular, the housing sleeve and the additional housing sleeve can be accessed from a rear seat compartment of a motor vehicle, extending towards the rear of a front seat. The housing sleeve and the additional housing sleeve are offset from each other in height. This allows the two housing sleeves to be used along a portion of the height of the motor vehicle seat, i.e., along a vertical distribution axis of the housing sleeves. The motor vehicle seat features a backrest with a housing sleeve and an additional housing sleeve. The backrest extends over a relatively large area, allowing the two housing sleeves to be integrated within this area without compromising the backrest's stability. The backrest is suitable for the arrangement of the housing sleeve and the additional housing sleeve. Especially in the case of two housing sleeves arranged relatively close to each other (for example, at a maximum distance of 20 cm apart), it is advantageous for the insertion opening and the additional insertion opening to be delimited by a common frame piece on the seat side. This allows for easy definition of the relative position of the two insertion openings. The invention further provides that at least one accessory has an additional insertable piece, wherein the insertable piece of the accessory can be inserted or is inserted into the insertion opening of the housing sleeve, and simultaneously, the additional insertable piece of the same accessory can be inserted or is inserted into the additional insertion opening of the additional housing sleeve. In this way, the same accessory can be fixed to two housing sleeves at the same time, creating a particularly stable arrangement.The distance between the two housing bushings helps to better absorb the bending moments that act through the insertable parts and in the housing bushings due to the weight of the accessory. For a particularly stable structure of the accessory, it is proposed that it have a bridge section from which the insertable piece and the additional insertable piece protrude, making a one-piece structure conceivable or also an interposition of other components (for example, adapters or joints). It is also preferable that the insert and the housing sleeve can be detachably locked together by means of a locking connection, to ensure that the insert is securely held in the housing sleeve. This also applies if the additional insert and the additional housing sleeve can be detachably locked together by means of an additional locking device. Each of the aforementioned locking devices can operate exclusively by form drag, for example, through form drag surfaces that cooperate with each other in a disengaging manner (in this case, it is preferable to have an actuating section to release the locking device). The aforementioned locking devices can also operate by both form drag and friction drag, for example, through wedge surfaces in contact with each other (in this case, the locking device may only be released by applying a corresponding pulling force, so an actuating section is not required, although it may be optional). In the case of two locking devices, it is preferable that the primary locking device and the additional locking device be coupled to each other in their movement and that at least one accessory have at least one actuating section, which, when actuated, allows the primary locking device and the additional locking device to be released simultaneously. This means that a mechanically adjusting drive, which acts in the case of an interlock between an insert and a housing sleeve, is released by actuating an actuating section. In particular, it is conceivable that there are two actuating sections that can be actuated in opposite directions and each transmits a drive motion to different drive elements of different locking devices. Another embodiment of the invention provides that the additional insertable part and the additional housing sleeve are connected to each other by friction. This arrangement can contribute to a particularly quiet operation (i.e., "no rattling"). At the same time, this arrangement allows for the absorption of high bending moments. In particular, it is preferable that at least one accessory include a bracket designed to support an electronic device weighing 1 kg or more. The ability to attach such an accessory to two mounting sockets simultaneously means that relatively heavy electronic devices can now also be secured to a motor vehicle seat, although lighter devices can also be attached to the bracket if necessary. Specifically, the electronic device can be a laptop computer or a monitor. The ability to absorb very high bending moments via two housing bushings contributes to the high safety of the motor vehicle seat arrangement in the event of a collision. Specifically, the motor vehicle seat arrangement is designed so that, when the accessory is inserted into the motor vehicle seat, it remains in place without being destroyed even if the accessory experiences an average acceleration of 30 g during a crash test. In a frontal or rear collision, the acceleration acts primarily along the longitudinal axis of the vehicle; in a side impact, primarily along a transverse axis of the vehicle. It is also preferable that the motor vehicle seating arrangement include at least one accessory designed, for example, as a coat hook, hanger, table, folding table, storage or waste container, umbrella stand or umbrella holder, drink holder, or holder for a smartphone, tablet, or camera. Each such accessory comprises an insertable piece and an additional insertable piece, and can be connected to the two housing sockets of the motor vehicle seating arrangement. In general, this results in a very flexible and at the same time safe use of motor vehicle seating arrangement accessories. Other features and advantages of the invention are described below.

A motor vehicle seat of a motor vehicle seating arrangement 10 shown in Figure 2 is designated with the reference sign 12 in Figure 1. The motor vehicle seat 12 has a backrest 14 with a front part 16 and a rear part 18. The rear part 18 has a boundary surface 20, which is formed, for example, by a lining or by upholstery fabric of the backrest 14. In the embodiment shown in the drawing, the backrest 14 extends to an upper section 22. Above the upper section 22 are two headrest rods 24 and a headrest 26 (only partially shown). In an embodiment not shown in the drawing, the backrest 14 extends continuously to the head area (the so-called integral seat with integrated headrest). A frame piece 28 is arranged on the boundary surface 20, which has two openings, in the form of an insertion opening 30 and in the form of an additional insertion opening 32. The insertion opening 30 is associated with a housing sleeve 34, which extends from the boundary surface 20 of the backrest 14 towards the front 16 of the backrest 14. The additional insertion opening 32 is associated with an additional housing sleeve 36, which also extends from the boundary surface 20 towards the front 16 of the backrest 14. Preferably, housing bushings 34 and 36 are identical in their dimensions. The housing bushings 34 and 36 have assigned insertion directions 38 and 40, indicated by arrows 38 and 40. The insertion directions 38 and 40 are parallel to each other and are oriented in the same direction; in the illustrated embodiment, starting from the bounding surface 20 towards the front part 16 of the backrest 14. When the backrest 14 is in the vertical position, the insertion directions 38 and 40 are oriented parallel to a longitudinal axis of the vehicle and can both point either forward in the direction of travel or backward in the direction of travel. In the embodiment illustrated in Figures 1 and 2, the housing sleeve 34 and the additional housing sleeve 36 are arranged laterally offset from each other, i.e., in the transverse direction of the vehicle. Each housing sleeve 34 and 36 serves to accommodate an insert, wherein an insert associated with the housing sleeve 34 is provided with the reference mark 42 in Figure 2, and an additional insert, which is associated with the additional housing sleeve 36, is provided with the reference mark 44. The insertable part 42 and the additional insertable part 44 each protrude from a bridge section 46, which spans the distance between the housing bushings 34 and 36 and which, together with the insertable parts 42 and 44, forms part of an accessory designated as a whole by the reference sign 48. In the illustrated embodiment, the accessory 48 comprises a joint 50 connected to the bridge section and a support 52 for an electronic device 54, which is configured, for example, as a monitor 56. A locking device 58 associated with the insertable part 42 and an additional locking device 60 associated with the additional insertable part 44 are provided to fix the insertable parts 42 and 44 in the housing bushings 34 and 36, see figure 3. In each case, two interlocking elements of the two interlocking devices 58 and 60 are coupled to each other in their movement through, for example, rod-shaped coupling elements 62, 64. The coupling element 62 is connected to a drive section 66, which is arranged adjacent to the insertable part 42. The coupling element 64 is connected to a drive section 68, which is arranged adjacent to the additional insertable part 44. By pressing the two actuating sections 66 and 68, two of the four locking elements of the two locking devices 58 and 60 can be simultaneously actuated in each case, so that the locking connections between the insertable part 42 and the housing sleeve 34 and, simultaneously, between the additional insertable part 44 and the additional housing sleeve 36 can be released. The motor vehicle seat arrangement 10 with the housing sleeve 34 and the additional housing sleeve 36 can also be used for an insertable part 42 and an additional insertable part 44 that are associated with accessories 70, 72 designed, for example, as hangers and / or as hooks, see figure 4. One embodiment of the motor vehicle seating arrangement 10 shown in Figures 5 and 6 has a structure comparable to the motor vehicle seating arrangement 10 described above with reference to Figures 1 to 4. Unlike the embodiment described above, the housing sleeve 34 and the additional housing sleeve 36 of the motor vehicle seating arrangement according to Figures 5 and 6 are offset from each other in height. Otherwise, reference is made to the above description with reference to Figures 1 to 4. With the arrangement of an accessory 48 with two insertable parts 42 and 44 and the offset in height of the housing sleeves 34 and 36, it is possible, unlike the illustration according to Figure 6, to dispense with an additional locking device for the locking connection between the additional insertable part 44 and the additional housing sleeve 36. In this case, it is advantageous to connect the additional insertable part 44 and the additional housing sleeve 36 solely by friction. In this respect, it is preferable that the additional housing sleeve 36 be arranged below the housing sleeve 34, so that the accessory 48 locks into the upper housing sleeve 34, with the lower additional housing sleeve 36 and its friction-fit connection with the additional insertable part 44 serving primarily to absorb bending moments.These bending moments are caused by the weight of the electronic device 54 and the accessory 48, and are transmitted to the additional housing sleeve 36 via the additional insertable piece 44. The motor vehicle seating arrangement 10 according to figures 5 and 6 also allows flexible use of other types of accessories 70 and 72, see figures 4 and 7. One embodiment of a motor vehicle seat arrangement 10 shown in Figure 8 also serves to detachably fix an accessory 74. The arrangement 10 according to Figure 8 comprises a mount 76 detachably or permanently fixed between the headrest rods 24 of the motor vehicle seat 12. The mount 76 has a housing sleeve 34 with an insertion opening 30. Accessory 74 features an insertable piece 42 that can be connected to the housing sleeve 34, preferably via a releasable locking device. Accessory 74 comprises an additional insertable part 44, which is connected to the insertable part 42 by means of a bridge section 46. The bridge section 46 is connected to the insertable piece 42 via a joint 50 and to the additional insertable piece 44 via an additional joint 78. A support 80, designed to hold a smartphone, for example, protrudes from the bridge section 46. To arrange the accessory 74 on the motor vehicle seat 12, the insertable piece 42 and the additional insertable piece 44 are oriented parallel to each other and inserted into the housing sleeve 34 of the mount 76 and into the additional housing sleeve 36 of the backrest 14 in insertion directions 38 and 40 parallel to each other and oriented in the same direction, and are locked there in each case. In the case shown in Fig. 8 where the backrest 14 is provided with two housing bushings, said arrangement comprises a third housing bushing 82 which, unlike the illustration in Fig. 8, allows use with an additional accessory, for example with an accessory 70 or 72 according to Fig. 7.
