- DE 102019 103460 A1 discloses a safety belt device with an electronic device, in which energy is transmitted inductively to a corresponding receiver unit in the belt strap via a transmitter unit arranged outside the belt strap. To compensate for the position of the webbing during use, several offset coils can be used as a transmitting and/or receiving unit.
- the invention is based on the object of specifying a safety belt device which enables improved transmission of electrical power and/or signals to a movable part of a safety belt device.
- a safety belt device with the features of claim 1 is proposed to solve the problem. Further preferred further developments can be found in the dependent claims, the figures and the associated description.
- a seat belt device for motor vehicles which includes a seat belt buckle with an insertion slot, a seat belt tongue that can be inserted into the insertion slot of the seat belt buckle and locked therein and has a belt tongue main body and a belt tongue cover, and a safety belt.
- the seat belt runs through a loop of the belt tongue.
- the belt buckle and the belt tongue be set up to transmit electrical power and/or signals from the belt buckle to the belt tongue.
- a transmission of electrical power and / or signals from the buckle to the belt tongue enables a corresponding transmission independently of fixed attachment points of a safety belt, which in the prior art is a simple transmission to a movable part of the safety belt device, in this case the safety belt, he - possible.
- so-called double retractors can be used for the safety belt device in a simple manner, which, in the case of a three-point belt, have separate refractors for the chest and lap belts. Accordingly, with such a seat belt device, there is no fixed attachment point of the seat belt available for transmission.
- the belt tongue can have one, two or more status displays, for example two status LEDs, which can display an inserted state and/or the state of a wireless data connection, for example using Bluetooth.
- the movable part of a seat belt device comprises a seat belt and a tongue.
- the seat belt lock and the seat belt tongue each have an inductor coil for the transmission of electrical power and/or signals.
- the two inductor coils enable contactless transmission of electrical power from the seat belt buckle to the seat belt tongue, as a result of which the transmission can be contactless and independent of any dirt.
- the transmittable power can be 2.5 W, for example.
- the two inductor coils can also be used alternatively or additionally for the transmission of electrical signals from the belt buckle to the belt tongue and/or from the belt tongue to the belt buckle.
- the inductor coil of the seat belt buckle is arranged in the area of the insertion slot for inserting the seat belt tongue.
- the area of the insertion slot is particularly suitable for the arrangement of an inductor coil in order to achieve the smallest possible distance from a belt tongue.
- the arrangement of the inductor coil in the area of the insertion slot can, for example, be in front of the insertion slot, in the insertion slot itself or in an intermediate position, so that the inductor coil is only partially arranged in the insertion slot.
- the inductor coil of the seat belt buckle is arranged on the opposite side of an unlocking button of the seat belt buckle in relation to the insertion slot.
- an opposite arrangement on the side facing away from the unlocking button enables a simplified design and enables the smallest possible distance between the inductor coil and the inductor coil of the seat belt tongue in order to achieve high transmission efficiency. Furthermore, in this way the inductor coil is covered by the seat belt tongue in a normal installation situation, which offers optical advantages.
- the inductor coil of the belt tongue is arranged above a locking section of the belt tongue main body in relation to the insertion direction.
- the inductor coil of the seat belt tongue does not have to be inserted over a long distance into the seat belt lock. Accordingly, the insertion slot and the locking mechanism, which engages in the locking section of the belt tongue main body, can be designed independently of the inductor coil.
- the inductor coil of the belt tongue is arranged on a main surface of the belt tongue main body, with the inductor coil being covered by the belt tongue cover.
- the main body of the belt tongue is made from sheet metal, for example, and therefore has two main surfaces, for example the front and rear.
- the main surfaces form the majority of the surface of the main body of the belt tongue.
- the inductor coil can be placed on one of the two main surfaces.
- the main surface that faces away from the unlocking button when the belt tongue is inserted is particularly suitable.
- a flat inductor coil can therefore be placed on the main body of the belt tongue in a simple manner, with the belt tongue covering, which is preferably made of a plastic, covering the inductor coil for mechanical protection.
- the belt tongue cover can also extend between the inductor coil and the belt tongue base body.
- the belt tongue in the inserted and locked state, has a freedom of movement along an insertion axis.
- the range of motion is limited on the one hand by a locked position of the belt tongue, in which the belt tongue cannot be pulled out further without pressing an unlocking button, and on the other hand by a pressed-in position of the belt tongue in which it is not possible to insert the belt tongue any deeper into the insertion slot.
- the inductor coil of the belt tongue and the inductor coil of the buckle are arranged concentrically to each other in a certain relative position in the range of motion.
- the pressed-in position of the belt tongue in which no deeper insertion of the belt tongue into the insertion slot is possible, is also referred to as the overtravel position.
- the locking position of the belt tongue in which no further extension of the belt tongue is possible without pressing an unlocking button, can also be referred to as the normal position.
- the relative position in which the inductor coil of the seat belt tongue and the inductor coil of the seat belt buckle are arranged concentrically to one another is arranged in a central area of the range of motion.
- the middle area is a partial section of the freedom of movement, which extends along an insertion axis of the seat belt buckle.
- the central area can, for example, have a distance from the limits of the range of motion of, for example, 20%, further, for example, 25% of the entire range of motion along the insertion axis.
- the belt tongue and the belt buckle each have a plurality of electrical contacts which, when the belt tongue is inserted and locked, produce a plurality of electrical connections for transmitting electrical power and/or signals between the belt buckle and the belt tongue.
- electrical power and/or signals can be transmitted from the seat belt lock without interference or loss via the electrical contacts on the seat belt tongue and the seat belt lock transferred to the belt tongue and/or from the belt tongue to the buckle.
- the contacts of the seat belt buckle are arranged on the other side of an unlocking button of the seat belt buckle in relation to the insertion slot.
- the unlocking button and the associated unlocking mechanism can be designed and implemented separately from the contacts of the belt buckle.
- the unlocking button can thus be carried out particularly easily up to the insertion slot.
- the contacts of the belt tongue are arranged above a locking section of the belt tongue main body in relation to the insertion direction.
- At least two electrical connections are provided for the transmission of electrical power and/or signals from the belt tongue to the seat belt.
- Electrical power and/or signals can be transmitted from a seat belt buckle to the seat belt via the seat belt tongue by means of two or more electrical connections between the seat belt tongue and the seat belt.
- electronic components in or on the seat belt can be operated and/or controlled.
- only electrical power can be transmitted from the seat belt buckle via the seat belt tongue to the safety belt or the devices provided therein or on it. henen electrical and / or electronic components are transferred. Signals can be transmitted between electrical and/or electronic components in the seat belt and other systems in a vehicle, for example via radio standards such as Bluetooth.
- a plug-in connection is provided on the bracket of the belt tongue, with the plug-in connection being arranged on the bracket on the side facing away from the direction of insertion.
- the plug-in connection is thus arranged on the side of the bracket which points in the pull-out direction of the belt tongue. Although this is also the direction in which any belt forces act, this side or surface of the bracket is unloaded.
- the plug-in connection on the belt tongue is therefore in an area which is not intended for the transmission of forces between the belt tongue and the seat belt.
- the clip of the belt tongue be folded over by a sewn loop of the seat belt, with a plug-in connection being provided on the seat belt, which is arranged inside the sewn loop of the seat belt.
- the sewn loop of the seat belt encloses the bracket so that two ends of the seat belt extend from the belt tongue, which can apply tensile forces to the bracket of the belt tongue independently of one another. At least two belt layers are sewn together. Such a sewn loop is particularly suitable for the use of two retractors for the chest and lap belts. Arranging the plug connection in the loop enables the plug connection to be protected by the safety belt, so that a user cannot get caught on the plug connection or manipulate it in a simple manner.
- the plug-in connection of the safety belt is arranged on a cable which emerges from the safety belt within the sewn loop.
- the cable on the plug-in connector allows the connection to be flexible enough to compensate for the mobility of the sewn loop around the buckle of the belt tongue, so that a connection between the plug-in connectors of the belt tongue and the belt buckle can be kept free of mechanical stress.
- the cable runs through a sewn section of the sewn loop of the safety belt.
- the cable can be passed between two sewn belt layers of the seat belt and held in the sewn section.
- the cable can run through the sewn section within a tubular belt layer of the safety belt and emerge inside the loop from the tubular belt layer into the sewn loop. Accordingly, the cable is fixed in position by the sewn portion.
- the cable has, at least in the sewn section, two lines which have a width greater than 2 mm, preferably greater than 4 mm, more preferably 6 mm.
- a correspondingly wide cable can be made very flat and at the same time offer a sufficient cable cross-section. This also significantly reduces the cable showing in the sewn section. Such a cable also offers a very high tolerance to puncturing, such as can occur when a sewing needle is used to produce the sewn section. Any puncturing reduces the line cross-section only minimally with the corresponding width, so that a high error tolerance can be achieved during production.
- a flexible printed circuit board be provided in or on the seat belt, to which electrical power and/or signals are transmitted from the seat belt lock via the seat belt tongue and via the seat belt.
- Various electronic components can be provided on the flexible printed circuit board for various functions such as a seat belt microphone, triggering of a seat belt airbag, occupant classification, lighting, vibration elements.
- the cable can be connected to a flexible circuit board in the sewn section, for example, or alternatively be integral with the flexible circuit board.

- FIG. 2 shows a belt tongue and a belt lock with inductor coils in a front view
- FIG. 3 shows a belt buckle with inductor coil and inserted belt tongue with inductor coil

- FIG. 6 shows a belt tongue with a sewn-on loop of a safety belt and a flexible guide plate
- FIG. 10 shows a seat belt lock with electrical contacts for a seat belt tongue.
- FIG. 1 shows an exemplary embodiment of a safety belt device 1 which is set up to inductively transmit electrical power and/or signals from the belt lock 2 to the belt tongue 4 .
- the belt tongue 4 has a belt tongue base body 5, which can be made of sheet metal, for example.
- the belt tongue base body 5 is partially encased by a belt tongue covering 6 .
- the section of the belt tongue 4 which is intended for insertion into the insertion slot 3 of a belt lock 2 has a recess which forms a locking section 11 of the belt tongue 4 .
- a locking mechanism of the belt buckle 2 engages in the locking section after the belt tongue 4 has been inserted into the insertion slot 3 .
- the locking section 11 can be embodied on the outer contour of the belt tongue 4 and have no recess. The locking can be released by an operator by pressing the unlocking button 10 .
- An inductor coil 9 is provided on the belt tongue 4 on the rear side or the side which is intended for orientation towards a passenger.
- the inductor coil 9 lies parallel to a main surface 12 of the main body 5 of the belt tongue, i.e. the main axis of the inductor coil 9 is perpendicular to the main surface 12.
- the inductor coil 9 lies above the locking section 11 in relation to an insertion direction B. Above the locking section 11 therefore means that the locking section 11 must always be pushed into the insertion slot 3 before the inductor coil 9 .
- the inductor coil 9 can also be pushed into the insertion slot 3 .
- the inductor coil 9 can also be pushed in partially, ie it can be provided in a transition area of the insertion slot 3 when the belt tongue 4 is in the inserted state.
- the inductor coil 9 is preferably covered by the belt tongue cover 6, so that the inductor coil 9 is mechanically protected from external influences.
- the seat belt tongue cover 6 is made of plastic, which means that the seat belt tongue cover 6 does not represent an obstacle to inductive power and/or signal transmission.
- the belt tongue 4 also has a bracket 8 through which the seat belt 7 is guided, so that forces from the seat belt 7 can be introduced into the bracket 8 .
- the bracket 8 is surrounded by the belt tongue cover 6, particularly on the side in the direction of insertion B, so that the edges of the metal belt tongue main body 5 can be rounded off by the belt tongue cover 6, which, among other things, reduces wear on the seat belt 7 minimized.
- Figure 2 shows the embodiment of Figure 1 in a front view intended to face away from the buckled body of a passenger, i.e. a passenger sees this side in particular when buckled.
- the inductor coil 9 of the belt tongue 4 is covered by the belt tongue 4 itself.
- the front view shows the position of the inductor coil 9 on the belt lock 2 .
- the inductor coil 9 is located on the belt lock 2 in the area of the insertion slot 3 and is covered by the housing 21 of the belt lock 2 .
- the insertion slot 3 is arranged between the inductor coil 9 on the one side and the unlocking button 10 on the other side, see FIG.
- the housing 21 is made of plastic.
- FIG. 3 shows the belt lock 2 with an inserted and locked belt tongue 4.
- the inductor coils 9 of the belt tongue 4 and the belt lock 2 are so close together that an inductive power transmission from the inductor coil 9 of the belt lock 2 to the Inductor coil 9 of the belt tongue 9 can be done.
- electrical current from the power supply of a motor vehicle can be made available to the belt tongue 4 .
- the belt lock 2 is preferably connected or can be connected to the vehicle electrical system of a motor vehicle, which is easily possible by means of cables and/or plug connections.
- an inductive signal transmission of electrical signals can take place by means of the two inductor coils 9.
- a plug-in connection 15 which enables electric power to be passed on to a seat belt 7 and/or for the transmission of electrical signals or data between the seat belt 7 and the seat belt tongue 4 .
- the plug-in connection 15 is arranged on the bracket 8 and is connected to the inductor coil 9 of the belt tongue 4 .
- This connection is preferably made via electronics (not shown) in the belt tongue 4.
- the arrangement of the plug-in connection 15 on the bracket 8 of the belt tongue 4 is provided in such a way that no force is introduced from the seat belt 7 to the belt tongue 4 in this area.
- the belt tongue 4 can have, for example, two status displays 22 in the form of two status LEDs. These can inform a user, for example, about the locked state of the seat belt tongue 4 via their lighting status, i.e. on, off, flashing and/or different lighting colors. Furthermore, for example, a status display 22 can display the status of a wireless data connection, for example from a seat belt microphone in the seat belt 7 to another system in the vehicle via Bluetooth.
- FIG. 4 shows the belt lock 2 with inductor coil 9 and inserted belt tongue 4 in a side view, in which the insertion axis A can be clearly seen.
- the belt tongue 4 is inserted with parts of the belt tongue main body 5 and the locking section 11 along the insertion axis A into the insertion slot and locked therein.
- the unlocking button 10 is actuated, the belt tongue 4 can be removed from the belt lock 2 along the insertion axis A in the opposite direction to the insertion direction B.
- the position of the seat belt tongue 4 in the seat belt buckle 2 in FIG. 4 corresponds to a position in which no further extraction of the seat belt tongue 4 from the seat belt buckle 2 is possible without actuating the unlocking button 10 .
- This position forms a first limit of the freedom of movement of the belt tongue 4 along the insertion axis A, which can also be referred to as the normal position.
- This position also called overtravel, forms the second limit of the freedom of movement of the belt tongue 4 along the insertion axis A.
- the freedom of movement relates only to the locked state; if the belt tongue 4 is released, the first limit of the freedom of movement is exceeded.
- the inductive transmission of electrical power and/or signals is possible in any position of the range of motion.
- the inductor coils 9 of the seat belt tongue 4 and the seat belt buckle 2 are optimally positioned in relation to one another in a middle position, ie not at one of the limits of the freedom of movement. In addition to the smallest possible distance, optimum positioning is achieved by a concentric arrangement of the two inductor coils 9 . In this case, the inductor coils 9 are not optimally arranged relative to one another in the normal position, which reduces the efficiency in this position, but offers the advantage that sufficient transmission of electrical power and/or signals is also possible in the overtravel position .
- the relative position of the coils 9 in the range of motion is shown schematically in FIG.
- the dashed spiral represents the inductor coil 9 of the seat belt buckle 2.
- the belt tongue 4 and thus the associated inductor coil 9 are in the normal position, in which no further extraction is possible without releasing the lock.
- the positioning of the inductor coils 9 relative to one another is therefore not optimal for an inductive transmission of electrical power and/or signals.
- the middle representation of FIG. 5 shows an optimal relative position of the inductor coils 9, in which the inductor coils 9 are arranged concentrically to one another.
- This relative position is taken in a middle area of the range of motion.
- the central area is therefore at a distance from the limits of the range of motion along the insertion axis A, with the distance being able to be, for example, 25% of the range of motion along the insertion axis A.
- the central area can be a distance of 35%, for example, or a further, for example, 45% .
- the optimal relative position is taken in the middle with equal distances to the borders between normal and overtravel position.
- the inductor coil 9 of a belt tongue 4 can be seen in the right illustration of FIG. 5 in the overtravel position, in which the locked belt tongue 4 is pressed deeply into the belt buckle 2, for example by a passenger's hand resting on it. A sufficient inductive power transmission is also possible in this position.
- FIG. 6 shows the belt tongue 4 with a safety belt 7 which has a sewn loop 17 which encloses the clip 8 of the belt tongue 4 . It is therefore not possible for the safety belt 7 to slide through the bracket 8 .
- the sewn loop 17 is closed by a sewn portion 18 connecting both ends of the sewn loop 17 to each other.
- Belt tongue 4 is suitable, for example, for a three-point belt with two refractors or
- the plug connection 15 on the bracket 8 is therefore largely covered by the sewn loop 17 and is only visible through the side openings of the sewn loop 17.
- the plug connection 15 of the bracket 8 is connected or latched to a plug connection 16 of the seat belt 7 .
- the plug connector 16 is attached to a cable 14, which allows sufficient mobility of the connection between the seat belt 7 or the outlet opening of the cable 14 and the connector 16 within the sewn loop 17 in order to compensate for movements of the bracket 8 within the sewn loop 17 be able.
- the cable 14 enters the sewn loop 17 via the inner surface thereof.
- the cable 14 can transmit electrical power and/or signals from the seat belt buckle 2 to a flexible printed circuit board 20 which is integrated into the seat belt 7 and enables various functionalities such as seat belt microphone, seat belt lighting, haptic warning devices, seat belt airbag deployment or passenger classification.
- the cable 14 and the flexible circuit board 20 can, for example, within a than
- Hose exported seat belt 7 be positioned.
- the cable 14 occurs within the sewn loop 17 in the preferably tubular seat belt 7 a.
- the cable 14 has at least two lines 19 for the transmission of electrical power and/or signals.
- the lines 19 of the cable 14 are guided through the sewn section 18 at a distance from one another. At least in this area, the lines 19 are comparatively wide, ie, for example, wider than 2 mm or, for example, wider than 5 mm. This means that the lines 19 can be made very thin, so that they do not show in the seat belt 7 .
- the lines 19 can be pierced during the manufacture of the sewn section 18, so that the seam runs through the lines 19 themselves.
- FIG. 7 shows a corresponding belt tongue 4 with an inductor coil 9 in an exploded view, wherein the belt tongue main body 5 with the two-part belt tongue covering 6 can be seen.
- the position of the inductor coil 9, which is covered on the outside by the belt tongue cover 6, can also be seen.
- the inductor coil 9 is electrically connected to the plug connector 15 .
- FIG. 9 shows an alternative embodiment of the seat belt tongue 4, which also enables transmission of electrical power and/or signals to a safety belt 7.
- the transmission to a safety belt 7 can take place in the same way as, for example, in the exemplary embodiment in FIG. 6. In contrast to the previous exemplary embodiments, there is no inductive transmission of electrical power and/or signals.
- the belt tongue 4 via which an electrical connection to a corresponding belt buckle 2, see Figure 10, can be made.
- the main body 5 of the belt tongue for example, can also be a contact, for example for ground.
- the electrical contacts 13 are aligned parallel to the insertion direction B and are positioned counter to the insertion direction B in relation to a locking section 11 .
- the parallel alignment enables a sliding contact in the range of motion along the insertion axis A.
- FIG. 10 shows a corresponding seat belt lock 2 with electrical contacts 13 below the insertion slot 3, which, when the seat belt tongue 4 is inserted, can establish an electrical connection with the electrical contacts of the seat belt tongue 4.
