Description

Technical Field

[0001] The invention relates to a movable seat cushion with a massage function placed on a motor vehicle seat, which comprises a support cushion which can be arranged in front of a motor vehicle seat backrest, a fastening device suitable for fastening the seat cushion to the motor vehicle seat and a plurality of actuators which are arranged on the support cushion. Background Art

[0002] Long periods of driving can cause stress to motor vehicle passengers, especially the driver. This can lead to exhaustion due to a combination of long concentration phases, an unchanging sitting position, insufficient air circulation between the passenger's back and the backrest of the motor vehicle seat, and motor vehicle seats that are not adapted or only inadequately adapted to the individual body dimensions of the passenger. These stresses not only make the driver uncomfortable, but can also endanger the driver's safety and the safety of other road users if signs of fatigue have a negative impact on the driver's performance.

[0003] One solution to reduce stress, especially for drivers, is to massage the back and buttocks while driving. Expensive motor vehicles often have motor vehicle seats with a massage function. Seat cushions with a massage function are a cheaper alternative. Such seat cushions can also be used flexibly in other environments, such as in the workplace on an office chair or at home for relaxation. The seat cushions are attached to the motor vehicle seat using straps, ties (rubber) or other fastening means.

[0004] Document CN205871798U introduces a seat cushion that provides a massage function through air pockets. The air pockets include massage points that are designed as small blocks that are filled and / or emptied by pumps and valves.

[0005] CN204432455U shows a seat cushion that uses pneumatic massage balls to achieve massage functions. These balls are accommodated in flexible rubber bags.

[0006] Seat cushions with massage function proposed in the prior art have disadvantages. Due to the technology used (small blocks or balls), the seat cushions are relatively thick. Additional components for controlling and operating the air pockets or massage balls take up space in the seat cushion itself or in the interior of the motor vehicle and may increase the risk of injury to passengers in the event of an accident. In the event of an accident, the side airbags installed in the vehicle seat may be covered and not be properly deployed. In addition, peripheral devices such as pumps, controllers, valves or power supplies cannot be securely accommodated in known seat cushions. As a result, vehicle passengers may be injured by flying parts.

[0007] For the above reasons, the law prohibits the use of such seat cushions with massage functions when riding or driving a motor vehicle. In addition, the passenger can feel the seat cushion even when not in use, which reduces the passenger's comfort. Summary of the invention

[0008] Therefore, an object of the present invention is to provide a removable seat cushion with a massage function that can be used and authorized to be used, in particular when riding or operating a motor vehicle. Another object of the present invention is to provide a seat cushion with a massage function that has no or few additional components or is of such a size that the risk of injury to a passenger is not increased by using the seat cushion.

[0009] The object of the present invention is therefore to provide a device for the interior of a motor vehicle, in particular a retaining device for a headrest, which retaining device remains locked in its position both when moving longitudinally and about a vertical axis due to strong forces such as those generated in a rear-end collision and cannot therefore fly around in the interior of the motor vehicle, thereby reducing the risk of injury to passengers.

[0010] This object is achieved by a movable seat cushion with a massage function according to the invention, which is placed on a motor vehicle seat. The movable seat cushion according to the invention has a massage function, and the support cushion can be arranged in front of the backrest of the motor vehicle seat. In addition, the movable seat cushion has a fastening device, by which the movable seat cushion can be fastened to the motor vehicle seat. A plurality of actuators and a receiving device suitable for receiving at least one peripheral device are arranged on the support cushion.

[0011] According to the invention, the receiving device can be positioned and in particular separately fastened at a spatial distance from the support cushion. Preferably, the receiving device is fastened to the rear of the backrest of the motor vehicle seat. The peripheral device contains the devices required for operating the seat cushion. This arrangement fixes the peripheral device when the vehicle is in motion and thus reduces the risk of injury to passengers, in particular due to rear-end collisions.

[0012] In another embodiment of the invention, the fastening means have straps. The straps are designed to be adjustable so that they can be adapted to different motor vehicle seats of varying sizes. The seat cushion according to the invention is therefore not limited to use in motor vehicles, but also in the workplace, for example on office chairs, and at home. At the same time, a secure connection of the support cushion to the motor vehicle seat is ensured; the support cushion cannot accidentally fall off or slip off.

[0013] In another embodiment of the invention, the strap is adapted to embrace the backrest of the motor vehicle seat, preferably in the lower area of ​​the seat cushion. This ensures a secure connection between the support cushion and the motor vehicle seat; the support cushion cannot accidentally fall off or slide off.

[0014] In another embodiment of the invention, the fastening device has a cover which can be arranged on the back of the backrest of the motor vehicle seat. The cover is located on top of the support cushion. The cover is connected to the cushion. The cover is designed to be adjustable so that it can be adapted to different motor vehicle seats of varying sizes, for example by Velcro fasteners. Thus, the seat cushion according to the invention is not only limited to use in motor vehicles, but also in the workplace, for example on office chairs, and in the home.

[0015] In another aspect of the invention, the cover has an opening for a headrest of the motor vehicle seat. The seat cushion according to the invention is placed over the headrest through the opening, so that the headrest is not covered by the seat cushion. Thus, the passenger can adjust the headrest at any time and any existing safety features (e.g., crash-active headrests) remain fully functional.

[0016] In another embodiment of the invention, the cover has fastening means connecting the cover to the support cushion. The fastening means of the cover can be arranged on the side of the backrest of the motor vehicle seat. The cover is connected to the cushion by means of the fastening means. At the same time, these fastening means connect the cover to the side of the backrest of the motor vehicle seat. The fastening means of the cover are designed to be adjustable so that they can be adapted to different motor vehicle seats of varying sizes, for example by Velcro fasteners. At the same time, the fastening means should be sized so that the side airbag remains fully functional in the event of an accident.

[0017] In another aspect of the invention, the peripheral device has a controller and / or a power supply. The controller is generally a microcomputer with operating elements, which has a corresponding program for controlling the massage process. Using the controller, the passenger can start the massage process, select from various massage programs, and end the massage process. The power supply is advantageously designed so that it can be operated by the electrical system of the vehicle. Power can be supplied, for example, from a socket (cigarette lighter), a USB connection, etc. In order to use the seat cushion outside the motor vehicle, a transformer can be inserted between the seat cushion and the socket.

[0018] In another embodiment of the invention, the receiving device is arranged on the cover of the seat cushion. Thus, the receiving device is arranged behind the backrest of the motor vehicle seat. This arrangement fixes the receiving device when the vehicle is in motion and thus reduces the risk of injury to passengers, in particular due to rear-end collisions.

[0019] In another aspect of the invention, the receiving device has a bag. The bag can be reclosed, for example, with a zipper. Thus, the peripheral device is easily accessible in the event of maintenance and can be easily replaced or repaired.

[0020] In another embodiment of the invention, the bag has a sound absorbing element. The sound absorbing element consists of foam, for example, and reduces the noise coming from peripheral devices.

[0021] In another embodiment of the invention, the actuators are arranged in a plurality of horizontal rows, preferably in 3 or more horizontal rows, and particularly preferably in 5 or more horizontal rows. Such an arrangement of the actuators makes it possible to massage a large portion of the passenger's back.

[0022] In another embodiment of the invention, the actuators are arranged in a plurality of vertically arranged rows. This arrangement of the actuators makes it possible to massage a large portion of the passenger's back and at the same time is very narrow so that the side airbag in the motor vehicle seat is not covered by the support cushion.

[0023] In another embodiment of the invention, the distance d between the vertical row and the center of the backrest is less than d=10 cm, preferably less than d=7.5 cm, particularly preferably less than d=5 cm. This arrangement of the actuators makes it possible to massage a large part of the passenger's back and at the same time is narrow enough that the side airbag in the motor vehicle seat is not covered by the support cushion. As a result, the side airbag can fully function in the event of an accident.

[0024] In another aspect of the invention, the foam layer is arranged over a substantial portion of the actuator.When not in use, the support cushion is barely noticeable to the passenger, as the support cushion adapts almost perfectly to the contours of the motor vehicle seat.

[0025] In a particularly advantageous embodiment of the invention, the actuators can be pneumatically operated. They are filled by an air pump and several valves and hose connections, which are all controlled by a controller.

[0026] The side of the support cushion facing the passenger consists of a flexible but strong fabric. On the side of the support cushion facing away from the passenger there is an inlet which is reinforced but flexible so that almost all the pressure generated by the pump and valve in the actuator is directed to the passenger's back. Compared with the seat cushions with massage function known in the prior art, the seat cushion according to the invention has the following advantages: the massage function can also be used while the motor vehicle is in motion. The absence of mechanical components such as massage balls reduces the risk of injury to the passenger in the event of an accident, while also increasing the comfort provided by the comprehensive massage function.

[0027] In another embodiment of the invention, the pneumatic actuators are cavitations. The actuators are designed as cavitations, which means that they are pneumatically filled and emptied by air. The seat cushion according to the invention offers the advantage that the massage function can also be used when the motor vehicle is in motion. The absence of mechanical components such as massage balls reduces the risk of injury to passengers in the event of an accident, while also increasing the comfort provided by the full massage function.

[0028] In a further embodiment of the invention, the peripheral device has a pump and / or one or more valves. The actuator is filled with air or emptied again via the pump and the valves.

[0029] In another advantageous embodiment of the invention, the pneumatic actuators can be filled individually in a better manner and / or independently of each other. This allows the passenger to select the most suitable massage program from a variety of programs and start and end it at any time.

[0030] In another aspect of the invention, each actuator has a direct hose connection to the pump. This allows the passenger to select the most suitable massage program from a variety of programs and to start and end it at any time. The hose is made of a soft, flexible material. The hose thickness of the hose connection is dimensioned so that the passenger does not or hardly notices the hose. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] The movable seat cushion 1 (with massage function) according to the present invention Figure 1 ) is fastened to a motor vehicle seat 99 and is ready for use, and has a support cushion 2, which is arranged on the front part 3.1 of the backrest 3 of the motor vehicle seat 99. In addition, the movable seat cushion 1 has a first fastening device, by means of which the movable seat cushion 1 is fastened to the motor vehicle seat 99. The motor vehicle seat 99 itself has a headrest 4 above the backrest 3.

[0038] The seat cushion 1 is fastened to the motor vehicle seat 99 by one or more first fastening means. The lower region of the support cushion 2 preferably has a strap on each side of the support cushion 2, which is guided around the lower region of the backrest 3 and surrounds the backrest 3. At the rear 3.2 of the backrest, two straps are connected to each other, for example, by adjustable clip fasteners or Velcro fasteners. A cover 5 with an opening 51 is arranged on the top of the support cushion 2. The size of this opening 51 is such that the headrest 4 of the motor vehicle seat 99 can pass through the opening. The cover 5 is connected to the support cushion 2 by second fastening means. These second fastening means connect the cover 5 to the side of the backrest 3 of the motor vehicle seat 99. The first fastening means and the second fastening means of the support cushion 2 and the cover 5 are designed to be adjustable so that they can be adapted to different motor vehicle seats 99 of varying sizes, for example, by Velcro fasteners. Therefore, the seat cushion 1 according to the invention is not only limited to use in motor vehicles, but also, for example, in the workplace on an office chair and at home. At the same time, a firm connection between the support pad 2 and the motor vehicle seat 99 is ensured; the support pad 2 will not accidentally fall off or slide off.

[0039] A plurality of actuators 20, 21, 22, 23, 24, 25, 26, 27, 28, 29 which perform the actual massage are arranged on the support cushion 2. The actuators 20, 21, 22, 23, 24, 25, 26, 27, 28, 29 are arranged in a matrix in horizontally arranged rows or vertically arranged columns, wherein 5 horizontal rows are particularly preferred. In this exemplary embodiment, a total of 10 actuators 20, 21, 22, 23, 24, 25, 26, 27, 28, 29 are arranged in 5 rows and 2 columns. This arrangement of the actuators 20, 21, 22, 23, 24, 25, 26, 27, 28, 29 makes it possible to massage a large part of the passenger's back and at the same time is very narrow so that the side airbag in the motor vehicle seat 99 is not covered by the support cushion 2. The distance d of the vertical columns is less than d=7 cm, particularly preferably less than d=3 cm. Therefore, the side airbags can fully function in the event of an accident.

[0040] The foam layer 2.1 is arranged over a large area of ​​the actuators 20, 21, 22, 23, 24, 25, 26, 27, 28, 29 so that the actuators 20, 21, 22, 23, 24, 25, 26, 27, 28, 29 are ideally completely covered by the foam layer 2.1. When not in use (empty actuators 20, 21, 22, 23, 24, 25, 26, 27, 28, 29), the support cushion 2 is not or barely perceptible to the passenger because the support cushion 2 adapts almost perfectly to the contours of the motor vehicle seat 99.

[0041] Compared with the seat cushions with massage function known in the prior art, the seat cushion 1 according to the invention also has the following advantages: the massage function can also be used while the motor vehicle is in motion.
