Description

Technical Field

[0001] The present invention relates to the field of vehicle technology and more particularly to a motor vehicle seat with an integrated child seat. Background Art

[0002] It is generally known to use specific safety devices for children in motor vehicles, such as separate child seats.

[0003] The disadvantage of this is that these usually bulky child seats must always be carried in the vehicle even if there are no children in the vehicle, which is inconvenient for vehicles (especially taxis, etc.).

[0004] WO 2012 / 135894 A1 discloses an inflatable child seat with an integrated compressor. DE 42 04224 C1 also discloses an inflatable child seat with an integrated inflation device.

[0005] US 7,413,249 B2 also discloses an inflatable child seat which is inflatable from a compressed air source and which is received in a recess in a backrest of a vehicle seat and can be inflated out of the backrest.

[0006] DE 103 16 816 A1 discloses a similar method, in which a recess for receiving a folded child seat is formed in the transition area between the backrest and the seat cushion.

[0007] DE 44 03 428 A1 discloses a motor vehicle seat in which the seat surface can be raised by applying pressure to a pocket arranged below it for seating a child. In addition, the motor vehicle seat may have an inflatable backrest part which must be suspended on the pillars of the headrest. Summary of the invention

[0008] A motor vehicle seat with an integrated child seat, wherein the child seat comprises an inflatable chamber which can be brought from a compressed, non-deployed state to an inflated, deployed state by a source of compressed air. Thus, the motor vehicle seat with an integrated child seat has simplified operation and improved safety.

[0009] As disclosed herein, when a child seat comprises a multi-stage inflatable air chamber, in particular a three-stage inflatable air chamber, which is fixed, in particular bonded and sewn, to the surface of a motor vehicle seat so as to be reinforced relative to each other, the child seat can be permanently carried in the vehicle without inconvenience and still be used in a simple manner.

[0010] In other words, the inflatable chamber is applied directly to the surface of the usual seat cover and can be inflated in a targeted manner at this point, wherein a choice can be made between three inflation sizes, wherein only one chamber, two chambers or all three chambers (and more in the case of a multi-stage embodiment) are inflated. Thus, the size of the child seat can be adapted to the size of the child, which additionally increases safety. Thus, with three stages, a more optimized seat adaptability can be achieved for children in the stages 3-6 years, 7-9 years and 9-12 years. Thus, the required biological and legal time periods after the so-called "cradle" stage and before the stage where there is no longer any requirement are completely covered.

[0011] Preferably, the air chamber is cross-linked and consists, for example, of a Kevlar reinforcement material.The outer layer is sewn transversely to the inner layer, in particular by reinforcing Kevlar yarns.

[0012] Advantageously, separate air chambers are provided for the seat surface, the headrest and the side ribs, so that these are also adaptable.

[0013] In order to improve the adaptability, it is further possible that the headrest and / or the backrest are adjustable by means of a motor so that they are adapted in position to the size of the child.

[0014] In an exemplary embodiment, the air chamber and / or the material of the air chamber comprises superimposed layers. These layers can be inflated in a targeted manner, for example, from the inside out, to adjust the size.

[0015] To this end, it is possible that the motor vehicle seat comprises a controller, a multi-way valve, in particular a three-way valve, and a compressed air source, so that the controller can act on the air chamber in a targeted manner via the valve from the compressed air source. This can be performed manually by pressing a button, or automatically when the seat is occupied by a child. The motor vehicle seat can then have a weight and height sensor connected to the controller in order to trigger the process of being inflated in a targeted manner.

[0016] In order to also adapt the position of the seat belt, it is preferably provided that the motor vehicle seat comprises a seat belt guide which can be adjusted by means of a motor. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] Further features and details of the invention are disclosed from the following description of the accompanying drawings, in which:

[0018] Figure 1 shows a plan view of a motor vehicle seat with an integrated child seat;

[0019] Figure 2 Shows Figure 1 a side view of a motor vehicle seat; and

[0020] Figure 3Shown through Figure 2 A cross-sectional view of a woven fabric in region X. DETAILED DESCRIPTION

[0021] The drawing shows a motor vehicle seat with an integrated child seat, which is designated overall by 1 .

[0022] The motor vehicle seat 1 comprises a seat surface 2 , a backrest 3 adjacent to the seat surface 2 and a headrest 4 .

[0023] The seat surface 2 is additionally provided with side ribs for lateral support.

[0024] The "second skin" and above it the "third skin" are sewn to the surface of the seat cover at suitable points 5, 6, 7 in order to configure an integrated child seat.

[0025] This forms an air chamber which can be inflated in three levels A, B, C and which can be inflated from the inside out to adapt to the size of the child seat.

[0026] Seat height and side support are adjusted by chambers 5A, B, C.

[0027] The lateral support of the trunk and the backrest length are adjusted by means of the backrest chambers 6A, B, C. For this purpose, the backrest 3 can also be height-adjustable by means of a motor.

[0028] The lateral support of the head and the upper body length of the child are adjusted by the headrest chambers 7A, B, C. For this purpose, the headrest 4 can also be height-adjusted by a motor.

[0029] Therefore, multiple levels of regulation are generated for children of different sizes, as shown in reference Figure 2 As indicated by the arrow in .

[0030] The woven fabric 8 of the chambers 5, 6, 7 comprises three layers A, B, C connected together, wherein the intermediate spaces each form one of a plurality of levels (see Figure 3 ).

[0031] Each chamber can receive compressed air from a compressed air source 12 (compressor or the like) via a three-way valve 9 in a targeted manner.

[0032] For this purpose, a control unit 10 is provided, by which the valve 9 , the compressed air source 12 and the electric drives for the backrest 3 and the headrest 4 are activated.

[0033] In addition, weight and height sensors 11 are arranged in the seat surface and the backrest and / or headrest, which sensors are also interconnected with the controller 10 so that when the seat is occupied by a child, the controller is able to inflate the chambers 5, 6, 7, which chambers 5, 6, 7 include the required layers A, B, C, and is able to move the backrest 3 and the headrest 4 in an appropriate manner, wherein, by adapting the headrest 4, the seat belt guide device 13 that is released at that time is also adjusted according to the height.
