  • Patent number: 8616614
    Abstract: An armrest structure for a vehicle of the present invention comprises a first armrest to support an elbow of one of arms of a passenger seated in a seat and a second armrest to support an elbow of the other arm of the passenger. A horizontal distance W1 between a vertically-extending seat center line of the seat and an elbow's support position at the first armrest is greater than a horizontal distance W2 between the vertically-extending seat center line and an elbow's support position at the second armrest, and a height H1 of the elbow's support position at the first armrest is greater than a height H2 of the elbow's support position at the second armrest. Accordingly, the passenger's elbows can be properly supported at the armrests on both sides, in a seat width direction, of the seat.

  • Patent number: 5466001
    Abstract: The head rest is detachably mounted to the seat back of the front seat and the air bag unit with an air bag mounted therein is mounted to the head rest. The air bag is expanded toward the passenger seated on the rear seat in response to an explosion signal from the control unit into which signals are entered from impact sensors. The air bag is so disposed as to expand only when the passenger is seated on the rear seat. The posture and position of the air bag unit is adjusted in association with the movement or displacement of the front seat to which the air bag is mounted, thereby improving the ability of the expanded air bag to confine the passenger seated on the rear seat and protecting the passenger in a more safe fashion. Further, the air bag unit is mounted to the head rest of the front seat, so that the air bag can be exchanged with ease and at cheap costs without exchanging the front seat itself.
