Description

[Detailed Description of the Invention] The present invention relates to a mounting bracket for a crank lock in a manual automobile door opening/closing device, which allows the crank rod of the manual automobile door opening/closing device to be easily attached to a seat rail for attaching a front seat. .

Conventionally, such mounting brackets have mounting holes that correspond to bolt insertion holes in the seat rail inserted through both ends of a long plate-shaped bracket body, are placed on the underside of the seat rail, and are sandwiched between the seat rail and the vehicle floor. However, the presence of the mounting bracket causes the inconvenience of raising the seat height, and the operating load of the crank rod in the opening/closing device is also applied to the seat rail via the mounting bracket, which is not the case with the existing seat rail. Since the addition of load is not taken into account, there are drawbacks such as excessive force being applied to the seat rail, causing deformation and the like, which may impede the sliding function of the seat.

In view of these drawbacks, the present invention forms a latching protrusion on one end of the long plate-shaped metal fitting body for latching one leg of the seat rail for attaching the front seat, and the other end for latching the other leg. Provided is a mounting bracket comprising a fixed piece placed on the upper surface of the mounting surface, which is protruded, a mounting hole is formed through the fixed piece, and a bearing for supporting a crank rod is fixed in the center of the metal fitting body. In order to solve the above-mentioned drawbacks, one embodiment of the present invention will be described below based on the drawings. Reference numeral 1 denotes a seat rail that supports the front seats 2, 2a in a slidable and adjustable manner; At both ends of the rail main body 4, which guides
9a is fixed.

10 is a stopper mechanism for the slide plate 3 relative to the rail body 4; 11 is a mounting bracket according to the present invention; one end of the long plate-shaped bracket body 12 has rib grooves on both sides of the upper surface of one leg 9 of the seat rail 1; 1
Latching protrusion 14, 1 inserted and latched onto 3, 13a
4a protrudes, and the latching protrusions 14,1
A contact surface 15 is formed at the base of the rail main body 4 so as to come into contact with the lower surface of the rail main body 4, and on which one end of the metal fitting main body 12 is hooked. In addition to forming a descending slope 16, a notch 17 is formed in the slope 16 corresponding to a portion that interferes with the leg portion 9a of the seat rail 1, and an end portion continuing from the notch 17 has an inward portion. A fixing piece 18 is provided in a protruding manner and extends toward the top and is placed on the upper surface of the mounting surface 6a of the leg part 9a.
A mounting hole 19 corresponding to the mounting hole 1 is provided through the mounting hole 1.
By inserting the bolt 7a through the bolt 9, the metal fitting main body 12 is attached and fixed onto the legs 9, 9a.

Reference numeral 20 denotes a bearing that rotatably supports both ends of the crank rod 22 of the door opening/closing device 21;
It is composed of a pair of receiving pieces 23, 23a made of synthetic resin, and the receiving pieces 23, 23a have the same shape divided into upper and lower parts, and a semicircular shape corresponding to the outer periphery of the crank rod 22 is provided at the center of the mating surface 24. A receiving part 25 is formed, and insertion holes 27, 27a for bolts 26, 26a are provided on both sides of the receiving part 25, and the peripheral edge of one of the insertion holes 27 is made to protrude from the mating surface 24 for fitting. A convex portion 28 is formed, and a fitting recess 29 that is depressed inwardly corresponding to the fitting convex portion 28 is formed at the peripheral edge of the other insertion hole 27a.
and the pair of receiving pieces 23, 23a are fitted and assembled at the mating surface 24 so that the fitting protrusion 28 and the fitting recess 29 face each other,
When assembling the crank rod 2 into the receiving part 25,
2 is inserted through the metal fitting body 12, and the bearing fitting 20 is screwed and fixed to the central lower surface of the metal fitting main body 12 with bolts 26, 26a.

In the figure, 30 is an operating lever for the crank lock 22, and 31 is an operating arm 33 that opens and closes the door 32.
This is a connecting rod that connects the crank rod 22 and the crank rod 22.

In short, the present invention forms at one end of the long plate-shaped metal fitting main body 12 the latching protrusions 14, 14a that are latched to one leg 9 of the seat rail 1 for attaching the front seats 2, 2a, and at the other end. is the mounting surface 6a of the other leg 9a
The fixing piece 18 placed on the top surface is provided protrudingly, and the fixing piece 18 is provided with a mounting hole 19 through it. Since the bolt 7 that fixes the leg 9 does not need to be removed because it is only hooked onto the leg 9 of the
Since the bolts 7a for fixing the leg portions 9a are simply overlapped and tightened through the mounting holes 19 on the mounting surface 6a of the seat rail 1, the mounting operation can be easily performed, and the mounting bracket 11 can be attached to the seat rail 1.
Since the seat rail 1 can be directly fixed on the vehicle floor 5, there is no problem of the front seats 2, 2a floating up due to the intervention of the mounting bracket 11. It is possible to prevent excessive force from being applied when operating the opening/closing device 21, and since the bearing 20 that supports the crank rod 22 is fixed to the center of the metal fitting body 12, the lower part of both ends of the front seats 2, 2a is fixed. Door opening/closing device 21 by mounting bracket 11 attached to
Its practical effects are enormous, such as being able to stably and rotatably support the crank rod 22, which is the main component of the engine.
