Abstract: A seat back comprises a support bracket in which a stay of a head rest is inserted, a guide bracket for supporting a rear surface of a vertically intermediate portion of the support bracket on the seat back frame, a head rest tilt mechanism, and a pressure receiving member which moves rearward when pushed by the body of an occupant. The head rest tilt mechanism includes slotted brackets each having a guide hole and slide members which individually movably engage the respective guide holes of the slotted brackets along the longitudinal direction thereof. The head rest tilt mechanism drives the sub-frame so that the head rest body tilts forward while moving upward as the slide members are moved upward along the guide holes when the pressure receiving member is moved rearward.

Abstract: An actuator includes a hollow cylinder which has a first portion and a second portion. The inner diameter of the first portion is larger than that of the second portion. A piston is inserted in the cylinder. The actuator has a gas generator which supplies a gas into the cylinder to move the piston toward the first portion. The seal member keeps airtightness between the piston and the cylinder when the piston stays in the second portion and flows the gas when the piston stays in the first portion. A hollow stopper is arranged in the first portion and stops the piston. The stopper has a vent groove which is provided on the inner surface and connects the interior of the cylinder to the open end. A piston rod is jointed to the piston and housed in the cylinder. The piston rod moves along the axis with the piston.

Abstract: When a vehicle is rear-ended and a seated user moves rearward in reaction to the rear-end collision, a load movement of a lumbar part of the seated user is sufficiently transmitted from a pressure plate of operating force generating means to an operating force generating mechanism, regardless of an amount of rearward tilting of a seat back. Then, a pressure roller serving as a driven member of the operating force generating mechanism largely deflects and sufficiently pulls inner cables of respective pulling cable devices, thereby smoothly moving both end portions of a headrest frame upward. As a result, the headrest frame is moved upward smoothly and reliably, and a headrest is moved in an upward-forward direction, that is, toward the head of the seated user smoothly and reliably.

Abstract: In the seat belt pretensioner device according to the present invention, because the buckle is pulled by urging an intermediate point of the cable, it is possible to pull the seat belt and buckle by a required stroke with a relatively small stroke of the power actuator, and this contributes to a compact design of the device. Because the buckle can be pulled via a fixed point of a cable guide, the buckle and, hence, seat belt can be pulled in a stable manner, and a high level of reliability can be achieved. For instance when the power actuator comprises a piston rod that is pushed out by high pressure gas, because a high pressure gas can be produced with a relatively small device, the size and weight of the device can be minimized.

Abstract: An actuator of an active knee bolster is provided with a drive force generation device and a one way lock mechanism that is disposed in a vicinity of an operation end of the drive force generation device. The one way lock mechanism is configured such that, if attempted movement of a piston member in an inward insertion direction occurs, respective engagement portions are moved to a taper portion by urging force of a spring, whereby the engagement portions are abutted against an external periphery surface of the piston member such that the piston member and the engagement portions are fixed. Accordingly, as a result of the one way lock mechanism, a main body of the active knee bolster that has been moved to a restraining position cannot return in a vehicle forward direction, and thus it is possible to generate a substantial lower limb restraining force that restrains a lower limb of an occupant.

Abstract: When a vehicle is rear-ended and a seated user moves rearward in reaction to the rear-end collision, a load generated by a rearward movement of a lumbar portion of the seated user is transmitted from a pressure plate of operating force generating means to an operating force generating mechanism. Then, a pressure roller of the operating force generating mechanism deflects and pulls inner cables of pulling cable devices, thereby moving both end portions of a headrest frame upward. As a result, the headrest frame is moved upward along with headrest supporting brackets smoothly and reliably, whereby a headrest attached to the headrest supporting brackets with headrest stays arranged between the headrest and the respective headrest supporting brackets is moved in the upward-forward direction, that is, toward the head of the seated user smoothly and reliably.
