Description

  The present invention is a seat for a vehicle, in particular, having a backrest disposed so as to be pivotable via a joint device, having a cloth tension main body and a seat cover that at least partially covers the main body, the joint device being a seat At least one joint part projecting upward from the base, the joint part projecting into a slit-like notch in the backrest, where the seat for the vehicle is joint-coupled with the notch, as well as such a seat It relates to a method for manufacturing.

  A vehicle seat of the same category is known from document DE-A 3800924A1. The seat described in this document is composed of a seat portion and a backrest that can be tilted with respect to the seat, each comprising a metal structure that is upholstered and equipped with a seat cover. From the metal structure of the seat portion functioning as the seat base, two joint portions spaced laterally with respect to the seating direction protrude upward, and these joint portions and the metal structure of the backrest separate another joint portion. The joints are joined via. In the region of the joint part protruding upward, slits are provided in the backrest upholstery and the seat cover, and these notches prevent collision between the joint part and the backrest during tilt adjustment. .

  Such sheet structures are widespread and have been demonstrated in practice. However, especially in the case of large slit-shaped notches associated with thin sheet upholstery, especially in the rear seats of the vehicle, the lower peripheral area of the upholstery part on the far side of the coupling device has a small rigidity, which There is a possibility that a problem arises that the tension of the seat cover is insufficient. This does not adversely affect the function, but may result in deterioration of the appearance of the sheet due to wrinkles or distortion.

  The object of the present invention is to provide the same category of sheets with improved appearance characteristics.

  The object is solved according to the invention by the fact that the lower edge of the seat cover in the area of the slit-like notch is equipped with means for accommodating a fixing element that can be joined to the seat base. As a result of this formation, it is ensured that the upholstery on the side of the backrest occupies their design position, even if the backrest has been significantly swung in advance, for example by folding forward on the seat portion. Therefore, the relevant area of the seat cover is always prestressed sufficiently and reproducibly at the design position.

  In order to allow attachment even when the upholstered area to be stressed is relatively large, according to a preferred embodiment of the present invention, the fixing element is releasably coupled with a fixing counter element located on the seat base It is suggested that

  The means for receiving the fixing element preferably comprises a pocket-shaped joining plate fitted in the seat cover. Advantageously, the fixing element is formed as a longitudinally extending, in particular cylindrical body, which is essentially parallel to the joint axis and is inserted from the slit-shaped notch into the seat cover joining plate. Is possible. Furthermore, the longitudinally extending body can then be fitted and / or plugged onto and / or into the locking counter element, preferably in the opposite direction along the longitudinal axis. For this reason, the main body extending in the longitudinal direction can be formed in a sleeve shape, and as a result, can be fitted to a cylindrical fixing opposing element. Since the fixing counter element can be formed as a screw head that can be used to fix the joint part to the seat base, the invention is essentially realized by a design change of the seat's natural components. Is possible.

  The seat cover is usually stretched downward in an upright backrest position by coupling the fixing element to the fixing counter element in order to achieve the desired position without wrinkling and distortion of the seat cover.

  The method for producing a seat according to the invention is characterized in that a seat base and a backrest that is upholstered and equipped with a seat cover and a coupling device are first produced. Next, the backrest is placed on the seat base, and the joint portion protruding above the joint device is joined to the seat base, forming a fixing element or a fixing counter element. By introducing the fixing element into the pocket, the necessary stress is applied to the seat cover.

  When both the fixing element and the assigned fixing counter element are used, the fixing element must be releasably positively connected to the fixing counter element previously connected to the seat base after being introduced into the seat cover. Is preferred.

  The drawings show, by way of example and diagrammatically, various embodiments of the invention.

  The vehicle rear seat bench 1 shown in FIG. 1 is composed of a seat portion 2 and a backrest 3, which has two joint devices 4 that can be locked if necessary separated from each other in the transverse direction with respect to the traveling direction. Accordingly, the sheet portion 2 can be turned around a horizontal rotation shaft 5. In the region of the joint device 4, the backrest 3 is provided with a slit-shaped notch 6 that leads upward from its lower edge.

  As is apparent from FIG. 2, each joint device 4 is composed of a first joint portion 8 projecting upward from the seat base 7, and this joint portion is disposed on the metal structure 9 of the backrest 3. Two joint portions 10 are jointed. The sheet base 7 can be a member that can be placed on the sheet portion 2 or a member that is on a component of the metal structure of the sheet portion 2. In the example given at the outset, the seat base 7 could also be integrated in the vehicle body. The first joint part 8 is fixedly connected to the seat base 7 via the joining plate 11 and by screws 12, 12 ', and only the foremost screw 12 is visible in FIG.

  The metal structure 9 of the backrest 3 is equipped with a cloth tension main body 13 covered with a seat cover 14. On the far side of the coupling device 4, the upholstered body 13 forms a wing 15 that is joined only at the top, which has a small stiffness and can be swung forward or backward during assembly of the screw 12. . In the lower region of the wing 15, the pocket 16 is built into the seat cover 14 and is opened only towards the screw 12. In this pocket 16, a cylindrical fixing element 17 extending parallel to the rotation shaft 5 is engaged, and in the use position of the backrest 3, the wing 15 is prestressed downward, and the seat cover 14 in this region is applied. Tighten. The fixing element 17 is directly formed in this embodiment as an extended screw head 18 of the screw 12, so that no additional members are necessary to carry out the invention. In principle, however, it is also possible to use a fastening element that is permanently connected to the joint part 8 by welding, for example.

  When manufacturing a vehicle rear seat bench, the backrest 3 equipped with the functional joint device 4 is placed on the seat base 7 so that the joint portion 8 can be fixedly coupled to the joining plate 11 with screws 12. Is done. For this reason, the wing 15 must be bent forward or backward so that the screw head 18 can be easily handled. Next, the screw head 18 is inserted into the pocket 16 by deforming the wing 15 again.

  If the wing has an inconvenient height / width ratio and / or its rigidity does not allow such deformation without damage, measures may be taken with the development shown in FIGS. it can.

  In the embodiments shown in these figures, the screw head 18 is formed shorter so that it does not protrude into the pocket 16 or only protrudes slightly. Thus, the complex deformation of the wing 15 when introducing the screw head 18 is slight or completely eliminated. Instead, a sleeve 19 corresponding to the pocket length is pre-inserted into the pocket 16 as the fixing element 17, and this sleeve is then mounted on a relatively short screw head 18 as a fixing counter element 20. Is indirectly coupled to the sheet base. As shown in FIG. 4, only a slight deformation of the wing 15 corresponding to the length of the screw head 18 is required.

  The removal of the backrest 3 is not hindered by the described specifications, because the prestress of the wing 15 is reversible by the withdrawal of the fixing element or the fixing counter elements 17, 20 from the pocket 16.
