Problems solved by technology

[0005] However, the space available for such a buckle feeder close to the seat is very limited, yet the structure of the buckle feeder must be able to reliably absorb the The force that occurs under the circumstances
For this purpose, in previously known designs of buckle feeders, the tooth engagement of the buckle feeder and the linear guide of the buckle feeder are positioned as far apart as possible, however this requires a great deal of space and in Tension is induced between the corresponding guides
An additional and difficult practical requirement imposed on such buckle feeders is the prohibition of making any noise when the buckle is extended and retracted, and especially in drive mode in premium vehicles; this would result in metal mating pairs being joined by plastic teeth And replacement of plastic parts, the plastic tooth connection and plastic parts are usually used for driving and guiding functions, however, these are difficult to meet crash load specifications

Embodiment Construction

[0052] The buckle feeder 11 has a flat, elongated shell-like housing 12 which is formed from a highly mechanically loadable material (in particular solid steel sheet) and which can reliably absorb shafts occurring at the buckle carrier 11 lateral and lateral forces, even in the event of a collision. The housing 12 is provided with threaded holes 14 near its lower narrow housing side 13 for seating on the vehicle body next to a vehicle seat (not shown). On the opposite side, a metal holding bar 16 protrudes from an angled wall along the upper narrow side 15 of the housing 12 , said holding bar 16 being provided on its end side 17 with a seating plate 18 for fitting a buckle 19 .

[0053] The lower region of the retaining rod 16 merges in several sections or preferably in one section into the coaxial mandrel 20 , the axis of which runs through the very center of the threaded hole 14 in this example. However, the mandrel 20 can also extend all the way to the seating plate 18 , s...

Abstract

The invention relates to a buckle feeder. In the case of an electric linear drive for a buckle feeder (11) with a spindle (20) axially displaceable by a spindle nut (21), avoiding the ) between the compact reduction gear (22) produces engagement fluctuations because the bending load on the mandrel (20) is absorbed by the rod (34) which approaches the mandrel in an axially parallel manner The shaft ( 20 ) or in said mandrel ( 20 ) is arranged, the rod ( 34 ) extending through a precise longitudinal guide ( 35 ) fixed to the device.

Description

technical field [0001] The invention relates to an object called a beltbuckle feeder according to the respective preambles of the two independent claims. Background technique [0002] In the buckle feeder known from DE 10 2012 016 211 A1, the buckle is arranged at the end of a spindle which is adjustable in height by means of a spindle nut. The motor required for the buckle feeder is mounted remotely from the buckle feeder and is operatively connected to the spindle drive via a flexible shaft. However, the efficiency of this arrangement is far from perfect, and the overall space requirement for mounting components remote from each other is considerable. [0003] According to DE 10 2011 008 775 A1, the buckle feeder also requires a separate installation space for the lifting gear and for the motorized drive of the lifting gear coupled via an external shaft. Here, the arbor is attached to the gear in a longitudinally fixed manner for linearly displacing the buckle head in th...
