Definitions

• the invention relates to a fitting for a vehicle seat, in particular for a motor vehicle seat, with the features of the preamble of claim 1.
• the shaft serves to transmit the unlocking operation between two basically identical fittings.
• the arranged within the fitting components are dimensioned so that even when summing on all tolerances of the fitting remains locked.
• it can come at very large tolerances to light rattling noises, which have a disturbing effect. To avoid the tolerances are to be kept low.
• the invention has the object of improving a fitting of the type mentioned. This object is achieved by a fitting with the features of claim 1.
• Advantageous embodiments are the subject of the dependent claims.
• the spring is preferably seated with a first leg on the shaft, wherein the first leg is preferably looped several times around the shaft to ensure a tight fit in the manner of a wrap spring brake, in particular for the function of axial.
• the first leg is preferably looped several times around the shaft to ensure a tight fit in the manner of a wrap spring brake, in particular for the function of axial.
• the spring is preferably supported by a second leg on the fitting, which then forms the counter bearing for the closing moment.
• This second leg is preferably largely stretched from the shaft and preferably has at the end of an outer hook, which engages behind the fitting, for example on the fitting base and / or on an attached to the fitting base adapter.
• the inventively designed fitting can be used for all types of vehicle seats with adjustable backrest, which should also be understood vehicle seats with a merely folding backrest.
• the fitting is used in pairs, when the operation of a shaft, which implements the transmission between the two fittings, is manually driven.
• 1 is a perspective view of the embodiment
• 2 is a schematic representation of a vehicle seat
• Fig. 3 is a view of the spring including radial section through the shaft
• Fig. 4 is another view of the spring together with the indicated side view of the shaft.
• a fitting 1 is provided for inclining a backrest 2 relative to a seat part 3 of a vehicle seat 5 in a motor vehicle and mounted on one side of the vehicle seat 5.
• a basically identical fitting 1 is mounted on the other side of the vehicle seat 5.
• the fitting 1 has a lower fitting part 11 as the first fitting part, a fitting upper part 12 which is rotatable relative to this second fitting part, a driver 14 and a horizontally arranged, profiled, hollow shaft 16 as transfer means to the other fitting 1.
• the geometry and arrangement of the shaft 16 defines the directional information used.
• an adapter 17 is attached, by means of which the fitting 1 is attached to the structure of the seat part 3.
• a holding plate 18 is attached, with which it is mounted together on the structure of the backrest 2.
• the holding plate 18 engages over the upper edge region of the fitting lower part 11 at least partially and thus ensures axial cohesion of the two fitting parts 11 and 12.
• the adapter 17 engages in the same way the lower edge of the fitting upper part 12 and thus acts as another holding plate.
• a spring 22 is provided which biases the shaft 16 against the actuating direction, i. by initiating a closing moment in the fitting the locking supports.
• the spring 22 is dimensioned so that its bias is very small compared to the actuation force to be applied for unlocking.
• the spring 22 is a specially wound leg spring.
• An inner, first leg 24 sits on the shaft 16 and is wrapped several times around this. The individual turns have towards the free end to a decreasing diameter.
• an inner hook 24 ' is formed, with which the first leg 24 engages approximately positively in the profile of the shaft 16.
• An integrally formed with the inner leg 24, outer, second leg 26 is largely stretched from the shaft 16 from.
• To support the spring 22 engages the outer leg 26 with an angled outer hook 26 'the lower fitting part 11 and the adapter 17 in the region in which two are arranged overlapping.
