Tongue presenter device and seat belt apparatus employing the same

Abstract

In order to improve the ease of handling of a tongue (5) and the smoothness of taking of the tongue (5) and not to make an occupant to experience discomfort when a belt conveying member (20) is set to a tongue grasping position (B), as a motor (23) rotates when a belt conveying member (20) of a tongue presenter device (10) is in a tongue storage position (A), an externally threaded shaft (16) rotates so that a lever supporting member (17) moves in a direction toward the front of a vehicle. During this, since a guide pin (22) is in a horizontal portion (21a 1 ) of a guide slot (21 a), a lever (19) is kept its inclined posture so that the belt conveying member (20) moves forward with keeping its level lower than a seat surface (2a 1 ). As the belt pin (22) reaches a sloping portion (21a 2 ) of the guide slot (21 a), the lever (19) takes a standing posture and the belt conveying member (20) is set to a tongue grasping position (B) higher than the seat surface (2a 1 ).

Problems solved by technology

[0010] However, in the seat belt transmitter device disclosed in the above-mentioned Patent Document 1, the link for setting the seat belt hook portion at the storage position passes from the rear lower part of the occupant sitting on the vehicle seat through the side of the occupant's waist or near it, protruding obliquely upward

Therefore, once the occupant sits on the seat, the seat belt hook suddenly protrudes upward from the seat surface of the vehicle seat near the occupant's waist or near the occupant's waist, and gets close to the occupant's eyes, thereby causing the occupant to feel uncomfortable.

[0011] And, under the state that sleeve type connecting rod is in the maximum extension, although the occupant can use the hand of setting safety belt hook portion side (that is, be right hand when safety belt hook portion is arranged on the right side of vehicle seat; When the seat belt hook is set on the left side of the vehicle seat, the left hand) holds the seat belt or the tongue, but the extended link interferes, and the occupant cannot smoothly hold the seat belt or the tongue

Therefore, the operation of the tongue when wearing the seat belt is not necessarily easy
