| 20090001786 | Recliner Mechanism - A recliner mechanism for a vehicle seat includes a support plate ( | 01-01-2009 |
| 20090039687 | LOCKING DEVICE FOR SEAT BACK - A locking device for a seat back includes release preventing means for preventing the locking device from being unintendedly released by the fact that a second arm portion of a lift lever abuts on a side edge portion of a guide hole of a lock plate to cause the lift lever to rotate positively when a base plate rotates forward along a horizontal direction about a lock pin in a state where the lock pin engages with a lock hole of the lock plate and the second arm portion of the lift lever is located in the guide hole of the lock plate when the seat back is held at a rising position. | 02-12-2009 |
| 20100096892 | Energy Absorption Device For Automobile Seat, and Assembly and Set Including Said Device - The invention relates to an energy absorption device in particular for the seat of an automobile in case of a shock, said device being substantially in the form of a plate including a succession of cutouts following each other in a deformation direction (X) between a first cutout and a last cutout and defining between them at least one bridge extending in a stretching direction (Y) transverse to the deformation direction (X), the first cutout having a shape slightly flaring in the stretching direction (X) towards the following cutouts. | 04-22-2010 |
| 20110018318 | MOVEABLE BACK PANEL FOR A VEHICLE SEAT - A vehicle seat having a seat back including an actuatable back panel. The back panel of the seat back may be moved between a normal, or flush position, and an actuated, or spaced position, relative to the seat back assembly. The back panel may be provided with connectors that may be used to connect the back panel to the seat assembly. The back panel is actuated in the event of a rear end collision to provide added clearance for penetration of an occupant's torso into the seat back without interference by seat accessories, such as an adjustable lumbar system, a bolster assembly, massage assembly, or a heating/cooling system. The seat accessories may be secured to the back panel as a sub-assembly to facilitate manufacture. A resilient member biases a linkage or torsion bar to automatically reset the back panel. | 01-27-2011 |
| 20110121623 | VEHICLE SEAT - A vehicle seat has a back frame, an elastic member interconnecting side supports of the back frame, a movable member on the elastic member, and a restriction on the back frame. The movable member and the restriction engage each other in a first mode when a rearward load on the elastic member is less than a given value and are released from one another in a second mode when the load on the elastic member equals or exceeds the given value. The restriction restricts a rearward movement of the movable member in the first mode to limit rearward bending of the elastic member. Rearward movement of the movable member is permitted in the second mode to release the limitation on bending of the elastic member. Thus, the vehicle seat protects an occupant's neck during a rear collision. | 05-26-2011 |
| 20110193379 | SEAT FRAME AND VEHICLE SEAT - A seat back frame and associated vehicle seat are provided for effectively reducing an input load applied onto a reclining mechanism at the time of rear surface collision, the frame and seat having an energy absorbing member fixed to a coupling portion of a lower frame for coupling left and right side frames on the lower side. Since the energy absorbing member is plastically deformable by pressing from the backrest front surface side, the energy absorbing member absorbs shock energy at the time of the rear surface collision to reduce an input load imposed onto a reclining mechanism. | 08-11-2011 |
| 20110215619 | SEAT BACK FRAMEWORK - In an upper frame member of seat back framework, an upward-slippage prevention portion is simply defined to prevent a seat occupant's back portion from being slipped or dislocated on and along a seat back in the case of rear-end collision. The upward-slippage prevention portion has a sloped region for receiving the seat occupant's back portion which is to be slipped or dislocated on and along the seat back under inertia when a rear-end collision occurs and thereby preventing an undesired upward slippage or dislocation of that seat occupant's back portion which will result in damage of his or her neck or cervical vertebrae. | 09-08-2011 |

If the support portion is displaced rearward in a longitudinal direction of the vehicle due to a rearward load that exceeds a prescribed magnitude being applied to the seat back, the contact portion comes into contact with the support portion on both the right and left sides of the seat back with respect to a center portion of the seat back. | 12-01-2011 |
| 20120098305 | SEAT BACK FRAME FOR VEHICLE SEAT - A seat back frame for the vehicle seat, includes a pair of side frames that are disposed on both sides in a seat width direction; and a supporting plate that has both ends connected to a bottom section of each of the side frames, wherein the supporting plate is at least disposed along an interval between a first height that corresponds to an upper part of a lumbar vertebra of an occupant seated in the seat and a second height that corresponds to a lower part of the lumbar vertebra, and curves in a manner such that, in a cross-section along with a vertical direction, the supporting plate bulges forward along a line from the first height to the second height. | 04-26-2012 |

| 20120181825 | SEAT BACK FRAMEWORK - A shoulder receiving portion is defined in each of two lateral frame members of seat back framework of vehicle seat in order to receive two shoulder portions of seat occupant in the case of rear-end collision, prior to a seat occupant's back portion being moved close to an upper frame member of the seat back framework. The shoulder receiving portion is therefore arranged in an upper region of each of the two lateral frame members so as to project forwardly from a plane where the two lateral frame members lie, and the upper frame member is formed in substantially “inverted-U” shape and inclined backwardly distant from the two lateral frame members, This arrangement avoids unpleasant pressed touch to be given to the seat occupant's back portion in the case of rear-end collision and may prevent a great impact from being imparted to vertebrae of the seat occupant. | 07-19-2012 |
