No. 11 IIM proposed a belt reacher device that actively encourages people to fasten their seat belts by tilting a rotary arm, to which one end of a seat belt is attached, forward in response to the closing action of a door. However, it is also possible to drive the rotary arm via a wire cable or the like using the force of closing the door. In addition, in such a belt reacher device, the rotary arm can be suitably driven by the tensile force of a control cable that has one end latched to the inner end of the door of a door checker provided on the door. can. However, since the rotary arm is driven using the closing force of the door, there may be an inconvenience that the force required to close the door increases.

れていると良い。According to the present invention, such an object is achieved by attaching an elastic body to the door checker that applies an urging force in the direction of closing the door. In particular, the elastic body is a tension spring that is fixed to the inner end of the door of the door checker, and the coupling point is between the pivot center of the outer end of the door checker and the other coupling point of the tension spring. It is preferable that the control cable is provided on the opposite side of the locking point of the control cable with respect to the straight line connecting the control cable.

。<Function> In this way, by exerting an urging force on the door checker in the direction of closing the door, the force required to close the door is reduced. In addition, by preventing the elastic body that reduces the door closing force from exerting moment force in an unfavorable direction on the door checker, the door checker exerts a side thrust force only in one direction against the surface of the door panel. Therefore, the support structure of the surface of the door panel to receive the side thrust force of the door checker can be simplified.

設けられたゴム製のストッパ部材である。The outer end 4a of the door checker 4 is pivotally connected to a link 3 fixed to the vehicle body in a known manner.
The inner end 4C of the control cable 6 has a spherical receiver surface 5 at its free end for locking one end of the control cable 6. A clamping body 7 for vertically clamping the main body portion 4b of the door checker 4 with elastic force is fixed to the inner surface of the door panel 1, and the control cable 6 is guided to the outer end of the clamping body 7. Guide slot 8 for
is cut out. The detailed configuration of the clamping body that clamps the main body portion 4b of the door checker 4 with elastic force in the vertical direction is omitted from the illustration to avoid complication. code 11
is a rubber stopper member provided at the end on the inner end 4c side of the main body portion 4b of the door checker.

。Further, a bracket 13 is fixed to the door panel 1, and a locking point B at the free end of the bracket 13 is connected to a locking point provided at an intermediate portion between the main body portion 4b and the inner end portion 4c of the door checker 4. A tension coil spring 12 is stretched between the two. At this time, the anchoring point A is connected to the control cable with respect to the straight line connecting the pivot center C of the outer end 4a of the door checker and the anchoring point B that anchors the other end of the coil spring 12, for reasons to be described later. It is provided on the side opposite to the locking part 6.

次に本発明に基づくドアチェッカの作動の要領について
説明する。Next, the operation of the door checker according to the present invention will be explained.

抗して支持される。As shown in FIG. 1, when the door is completely closed, the pulling stroke for the control cable 6 has a maximum value of 5IIlaX, and the control cable 6 is pulled into the inner end 4C of the door checker 4. The biasing force of the tension coil spring 12 takes a relatively small value. The control cable 6 exerts a counterclockwise moment force around the pivot center C of the door checker 4 in the counterclockwise direction in FIG.
The main body portion 4b of the door checker 4 is supported against the moment force.

ーブル６の引張り力は極めて小さい（直となっている。FIG. 2 shows the door rotated around the rotation center 2 in the direction of arrow E and brought into a substantially fully open state, and the door checker 4
The pulling stroke on the control cable 6 due to the minimum value S is 11n. Since the driving force of the control cable 6 is required only when the door is near the fully open position, the tensile force of the control cable 6 is extremely small when the door is in the fully open position shown in FIG. It is direct.

従って上記いずれの場合に於ても、軸受Ｏ−ラ９と対向

As a result, a large load is applied to the portion 10, and the portion 10
wear out. Although it is conceivable to use a structure similar to that of the bearing roller 9 for the portion 10, there arises the disadvantage that the structure of the holding body is complicated and the manufacturing cost increases. Therefore, if one end of the tension coil spring 12 is attached to point A as shown in FIG. 1, the side thrust force generated by the moment force against the door checker 4 will be constantly supported by the bearing roller 9. Therefore, the clamping body 7
The configuration can be simplified, and no backlash will occur.

In addition, by appropriately determining the locking position of an elastic body such as a tension coil spring used for such a purpose, it is possible to avoid a situation where the door checker 4 generates a side thrust force in an undesirable direction. This has the effect of simplifying the structure of the holding body for the checker.
