Description

The invention relates to a seat device for a vehicle, with a first element, in particular a backrest, and with a second element, in particular a seat cushion, which can be handled separately from the first element and can be fed to the first element, around the second element for forming the seat device on the to fasten the first element, the first element having a carrier and at least one hook element fastened to the carrier, the hook element having a retaining portion which, when the second element is fed, forms a guide for a counter-hook element of the second element, through which the counter-hook element is inserted into a Behind grip area is guided, wherein the counter hook element engages behind the hook element when the counter hook element is located in the rear grip area.

Seat devices of the type mentioned are known. For example, multi-part seat devices are often installed in vehicles. The seat devices thus have at least a first element and a second element, wherein the second element can be handled separately from the first element and fed to the first element in order to fasten the second element to the first element to form the seat device.

In order to enable the second element to be attached to the first element, it is known to attach at least one hook element to a carrier of the first element. The second element then has a counter-hook element, by means of which the second element can be fastened to the first element, more precisely to the hook element of the first element. For this purpose, the hook element fastened to the carrier has a retaining section which, when the second element is fed to the first element, forms a guide for the counter-hook element of the second element. The retaining section is shaped in such a way that the counter-hook element is guided through the guide into a rear grip area, at least when the second element is fed to the first element along an intended feed direction. The rear grip area is an area located in front of the retaining section in the feed direction. If the counter-hook element is located in the rear grip area, the counter-hook element engages behind the hook element. The hook element then prevents the second element from separating from the first element counter to the feed direction. If the seat device is arranged in the vehicle in such a way that a forward direction of travel of the vehicle is at least substantially opposite to the feed direction, the fastening of the second element to the first element prevents the second element from moving, for example in the event of an emergency braking process or an accident in the vehicle detaches from the first element.

From the patent specification DE 695 00 681 T23 a seat device of a vehicle is also known which has a pivotable backrest. In order to fasten the backrest to a stationary part of the vehicle, the stationary part has a hook element and the backrest has a counter-hook element.

The disclosure document DE 10 2015 121 118 A1 discloses a vehicle seat of a vehicle. The vehicle seat has a seat cushion with a seat cushion wire, the seat cushion wire being arranged in a receiving device of a support structure of the vehicle. A crash hook is also attached to the seat cushion and engages in an eyelet of the receiving device, so that in the event of a crash of the vehicle the seat cushion wire is caught by the crash hook in the receiving device.

It is also known from practice to use an S-shaped curved hook element as the hook element, which has two eyes due to the S-shape and is fastened to the carrier by one of these eyes.

The invention is based on the object of providing a seat device which, compared with previously known seat devices, enables the second element to be fastened to the first element more easily.

The object on which the invention is based is achieved by a seat device having the features of claim 1. According to the invention, it is provided that the hook element is fastened to the carrier in such a way that the carrier is arranged at least in some areas in the rear grip area. The carrier is therefore located in front of the retaining section in the feed direction. The carrier is preferably arranged as a whole in the rear grip area. The guide of the counter-hook element into the rear grip area is therefore not hindered by the carrier. Instead, the counter-hook element is guided securely into the rear grip area by the design of the seat device according to the invention.

The advantageous shape of the hook element means that it has only one, in particular, open eyelet, which serves to receive both the counter-hook element and the carrier. The first element is preferably a backrest of the seat device. The second element is preferably a seat cushion of the seat device. The seat device is for example a seat of the vehicle or around a single seat of the vehicle. The carrier is preferably an elongated element, for example a transverse tube of the backrest, the longitudinal extent of which runs in the transverse direction of the seat device. The hook element is preferably designed to be pressure-resistant. The second element can then be held back particularly reliably by the hook element in the event of an emergency braking process or in the event of an accident.

According to a preferred embodiment it is provided that the hook element has a fastening section, in particular in the form of a circular path, which engages around the carrier at least in some areas. For this purpose, the carrier expediently has an outer contour which, at least in sections, corresponds to the shape of the fastening section, in particular in the form of a circular path. In this way, an advantageous contact surface between the hook element and the carrier and thus a stable attachment of the hook element to the carrier is achieved.

The retaining section preferably has a straight-line section, the straight-line section tangentially adjoining the fastening section in the form of a circular path. Preferably, the straight-line section below the circular fastening section adjoins the circular fastening section tangentially. Terms such as “below” and “above” relate to the seating arrangement that is intended to be arranged in the vehicle. By providing the straight-line section, a vertical extension of the rear grip area is enlarged, so that there is sufficient space for the carrier and the counter-hook element in the rear grip area. According to a preferred embodiment it is provided that the hook element has a semi-teardrop-shaped longitudinal section. The half-drop shape preferably consists of a circular section and a straight-line section, the advantages of these sections having been described above.

According to a preferred embodiment it is provided that the hook element is designed in the form of a wire. The hook element thus has a longitudinal extension and a transverse extension, the longitudinal extension being significantly greater than the transverse extension.

The wire-shaped hook element preferably has a round or oval-shaped cross section. As a result of such a configuration of the hook element, the hook element does not have any sharp edges which could damage parts of the seat device or other parts of the vehicle.

The hook element and the carrier are preferably welded to one another. This ensures that the hook element is securely fastened to the carrier. Due to the wire-shaped design of the hook element, in relation to the transverse extension of the hook element, there is a particularly large contact surface that can be used for welding between the hook element and the carrier.

According to a preferred embodiment it is provided that the first element has a first hook element and a second hook element, the hook elements being attached to the carrier at a distance from one another in the longitudinal extension of the carrier. The provision of two hook elements ensures particularly secure attachment of the second element to the first element. Because the hook elements are spaced apart from one another, tilting of the second element attached to the first element by means of the hook elements is also avoided. In particular, the hook elements are designed the same. The two hook elements preferably differ from one another. For example, one of the hook elements has a greater longitudinal extension than the other of the hook elements.

According to a preferred embodiment it is provided that the hook elements are part of a hook bracket. A part is therefore provided in addition to the carrier, by means of which the two hook elements are connected to one another. As a result, the hook elements can be handled together and can be easily connected to the carrier at a desired distance from one another and in a desired orientation. The hook elements and the part connecting the hook elements are preferably formed in one piece with one another, so that the hook bracket is formed in one piece as a whole.

According to a preferred embodiment it is provided that the counter-hook element is elastically displaceable. For example, when the second element is fed to the first element, the counter-hook element is displaced elastically against a spring force when the counter-hook element is pressed against the retaining section forming the guide. If the counter-hook element is passed over one end of the guide, the counter-hook element is displaced back by the spring force, so that the counter-hook element engages in the area where it engages behind. Because the counter-hook element is elastically displaced by the hook element, the second element itself can at least substantially along the first element fed in a straight feed direction in order to fasten the elements together. As a result, only a small amount of free installation space is necessary to feed the second element to the first element.

According to a preferred embodiment it is provided that the second element has a wire frame, the counter-hook element being formed by a wire at a free end of the wire frame. The wire frame is elastically deformable, so that the elastic displaceability of the counter-hook element is advantageously provided by the provision of the wire frame. The wire frame is preferably fastened to the second element in such a way that the wire at the free end of the wire frame, that is to say the counter-hook element, is translationally displaced by the retaining section when the second element is fed to the first element. An alignment of a longitudinal axis of the wire is therefore not changed when the wire is elastically displaced by the retaining section. This avoids tilting of the wire when the second element is fed to the first element, which could make it more difficult to guide the wire into the rear grip area.

The invention is explained in more detail below with reference to the drawings. To do this, show:

• 1 a vehicle with a seating arrangement,
• 2 a detailed view of a hook device of the seat device and
• 3 a perspective view of the hook device.

1 shows a vehicle 1 with a seating arrangement 2 . With the seating arrangement 2 In the present case, it is a bench 2 of the vehicle 1 . Alternatively, it is the seat device 2 around a single seat of the vehicle 1 . The seating arrangement 2 has a first element 3 on that stuck with the vehicle 1 connected is. With the first element 3 it is a backrest 3 the seating arrangement 2 . The first element 3 has an elongated support 4th on, which is in a lower area of the first element 3 is arranged. The carrier 4th is arranged such that a longitudinal extension of the carrier 4th parallel to a transverse extension of the seat device 2 runs.

The seating arrangement 2 also has a second element 5 on. The second element 5 In the present case, it is a seat cushion 5 the seating arrangement 2 . How out 1 can be seen is the second element 5 from the first element 3 can be handled separately. The 1 the first element 3 and the second element 5 in a separate state. The second element 5 has an elastically deformable wire frame 6th on. The wire frame 6th has a wire at one free end 7th on, which is a counter-hook element 7th trains. The counter hook element 7th is under elastic deformation of the wire frame 6th elastically displaceable. The counter hook element 7th protrudes over a rear end 33 of a base body 34 of the second element 5 out.

For assembling the seating arrangement 2 is the second element 5 the first element 3 feedable to the second element 5 on the first element 3 to fix. For example, the second item is 5 the first element 3 do this along a through the arrow 8th described trajectory fed. Is the seating arrangement 2 mounted, so is the second element 5 by means of the counter-hook element 7th on the first element 3 attached. The counter hook element 7th then works with an in 1 non-apparent hook device attached to the carrier 4th is attached together such that a separation of the second element 5 from the first element 3 by one in the forward direction 9 of the vehicle 1 on the second element 5 acting force is prevented. Such a force acts on the second element, for example 5 when the vehicle 1 quickly decelerated, for example due to an emergency braking or an accident of the vehicle 1 .

According to the in 1 illustrated embodiment has the second element 5 also a fastener 10 on, which is in the front area of the base body 34 located and the part of the wire frame 6th is. The vehicle 1 has a counter fastener 11 on that on a floor of the vehicle 1 is arranged. In the assembled state of the seating arrangement 2 is the second element 5 by means of the fastening element 10 on the counter-fastener 11 attached.

2 shows a longitudinal section through the seat device 2 in the area of the carrier 4th . How out 2 can be seen, has the first element 3 the hook device 12th on. The hook device 12th has a first hook element 24A and a second hook element 24B, the hook elements 24A and 24B in the longitudinal extension of the carrier 4th spaced from each other with the carrier 4th are connected. Except for one in the forward direction 9 extending end portion 25B is the second hook element 24B in FIG 2 covered by the first hook element 24A. The following essentially describes the configuration of the first hook element 24A. Because the hook elements 24A and 24B differ from one another only in that the second hook element 24B additionally has the end section 25B, the features disclosed with regard to the first hook element 24A also apply to the second hook element 24B.

The first hook element 24A has a fastening section 26A in the form of a circular path and a straight-line section 27A, which connects tangentially to the fastening section 26A in the form of a circular path. The first hook element 24A thus has an overall half-teardrop-shaped longitudinal section. The circular fastening section 26A and the straight-line section 27A together form a retaining section 28A. At an area 29A, which is in the forward direction of travel 9 is located behind the retaining portion 28A, it is a rear grip area 29A. It is assumed that the counter-hook element 7th the retaining portion 28A engages behind when the counter-hook element 7th as in 2 shown is located in the rear grip area 29A. The retaining portion 28A then prevents separation of the second element 5 from the first element 3 by one in the forward direction 9 on the second element 5 Acting force. The first hook element 24A is thus on the carrier 4th attached that the circular fastening portion 26A one in the forward direction 9 front part 30th of the wearer 4th encompasses. The carrier 4th is accordingly arranged in the rear grip area 29A. The retaining section 28A accordingly forms an open eye which is used both for receiving the counter-hook element 7th as well as to accommodate the carrier 4th serves.

Used to assemble the seating arrangement 2 that of the first element 3 separate second element 5 for example along one through the arrow 20th feed direction shown to the first element 3 supplied, then hits the counter-hook element 7th onto the retaining portion 28A. Strikes the counter-hook element 7th below an apex 31A of the retaining section 28A onto the retaining section 28A, the counter-hook element becomes 7th displaced elastically downward by the retaining section 28A, in particular by the straight-line section 27A, and guided into the rear grip area 29A. The retaining section 28A thus forms a guide for the counter-hook element 7th . Because the hook element 24A is so on the carrier 4th is attached to that of the carrier 4th is arranged in the rear engagement area 29A, the guide of the counter-hook element 7th into the rear grip area 29A by the wearer 4th not disabled. The vertex 31A is also so high that a meeting of the counter-hook element 7th on the retention portion 28A above the apex 31A is extremely unlikely.

3 shows the in 2 shown hook device 12th in a perspective view. As can be seen, the first hook element 24A and the second hook element 24B are each wire-shaped. The hook elements 24A, 24B each have a round cross section, so that the hook elements 24A and 24B are formed without edges. The hook elements 24A and 24B are with the carrier 4th welded. Due to the wire-shaped design of the hook elements 24A and 24B, the hook elements 24A and 24B are particularly stable with the carrier 4th weldable.

How out 3 can also be seen, has the hook device 12th a part 32 by which the hook members 24A and 24B are connected to each other. The hook elements 24A and 24B as well as the part 32 therefore together form a hook bracket 35 out.
