用いられるようになってきた。This type of seat adjuster is a pair of left and right rail combinations formed by slidably connecting a fixed side rail fixed to the floor side of the vehicle body and a movable side rail attached to the seat side.
A one-sided locking system in which a locking mechanism for locking a fixed rail and a movable rail is disposed only on one rail assembly, and a double-sided locking system in which a locking mechanism for locking a fixed side rail and a movable rail is disposed on both rail assemblies, respectively, are used. However, in the case of the one-side locking system, the rails of the other rail assembly are in a slidable state, so in the event of a sudden stop, the pressing force may be applied to the seat unevenly, causing the seat frame to deform. It is necessary to increase the rigidity by attaching reinforcing members, etc., which increases the weight and cost.Also, from the viewpoint of safety measures, the double-sided locking method has come to be widely used.

を要していた。This double-sided four-way seat adjuster is constructed by disposing a primary locking mechanism on one rail assembly and disposing a secondary locking mechanism that operates in conjunction with the primary locking mechanism on the other rail assembly. However, the conventional secondary locking mechanism is configured in a pfJ manner with the primary locking mechanism, that is, the stopper has a substantially rectangular tooth profile with a flat tip and the tooth profile of this stopper is t! One of the lock grates with tooth profiles of the same shape or the lock grates with a rectangular retaining hole in the longitudinal direction with a width comparable to the width of the tooth profile of the stopper is used as the fixed side rail, and the other is used as the movable side. It is constructed by being attached to the rail respectively, and is constructed by the engagement between the teeth of the stone and the arm and the teeth of the lock grate, or the engagement between the teeth of the stopper and the rectangular engagement hole of the lock grate. lock and
It is configured to prevent sliding. However, when the locking mechanism operates and meshes or engages, there is no space between the teeth of the stone/+- and the teeth of the locking grating or the rectangular retaining hole, so there is no space between the teeth and the frame that makes up the seat. If the parts are distorted or there is a slight deviation in the installation of the left and right rail combinations, the engagement or retention between the primary locking mechanism and the secondary locking mechanism may be misaligned, resulting in locking on both ends. Since the mechanisms cannot operate at the same time, high precision of the seat frame is required, and it takes time and effort to align the rail joints when assembling them.

In the mating relationship, the seat is formed so that there is a margin in the initial state of the meshing or engagement operation, and that they are brought into close contact at the end of the operation, so that the secondary locking mechanism is interlocked with the primary locking mechanism and the locking operation can be performed at the same time. It provides an adjuster.

Also, at the start of this meshing, the teeth of the lock plate (2) and the teeth of the stone/4'-grate (c) are t! Since they are in sliding contact at right angles, the mechanical resistance during sliding contact is small and engagement can be easily performed.

Although the locking mechanism described above is used as the primary locking mechanism on one rail joint A side, a locking mechanism that can perform the above-mentioned automatic meshing positioning may also be used. Of course, it is also possible to configure a one-sided locking mechanism by installing it only on body A or A'.

できて作業能率が向上される等実用的効果が大である。As described above, in the seat adjuster according to the present invention, at least the front half of the teeth formed on the lock grating and the stopper grate of the secondary locking mechanism is formed into a tapered shape, so that the tooth pieces between the two grates are formed in a tapered shape. It is possible to provide a sufficient range of engagement at the start of engagement, and when assembling the parts that make up the seat, there is no problem that the synchronous four-way operation of the primary and secondary opening mechanisms becomes impossible due to distortion that occurs later. This is not a stupid problem that can be solved, but the tooth pieces of the mouth, fugrate, and stock/mother-grate are bent at the required angle from the middle part, so that the tips of the tooth pieces that mesh with each other start meshing with almost right angles. Even when the tooth pieces are in contact with each other, they move while sliding smoothly on each other's tapered edges, and at the end of the meshing operation, both tooth pieces mesh tightly with each other, completely inhibiting back and forth movement. , the movable side rail can be reliably locked to the fixed side rail. In this way, the secondary locking mechanism performs its locking operation in complete synchronization with the primary locking mechanism, so that the seat is securely held in place, providing a sense of stability, and is also effective in terms of safety measures. Moreover, in manufacturing, there are no problems with precision in positioning between the primary and secondary double-ended locking mechanisms, and the assembly process can be simplified and work efficiency can be improved, which has great practical effects.
