Described are passenger seats having a seat frame and a seat bottom slidingly and pivotally attached to the seat frame that, when the passenger seats are reclined, are configured to articulate forward from an upright configuration of the passenger seat to a second seat position corresponding to a reclined configuration of the passenger seat. The seat bottom can include an aft articulating mechanism that defines a declining first path in an aft-to-forward direction to cause the aft end of the seat bottom to drop when the seat bottom articulates forward; and a forward articulating mechanism connected with the seat bottom near a forward end of the seat bottom that defines a second path shaped to cause the forward end of the seat bottom to move upward when the seat bottom articulates forward, such that the seat bottom tilts aft in response to articulating forward when the passenger seat is reclined.

An object of the present invention is to provide a vehicle seat in which a vacant space produced after tipping up a seat cushion can be effectively used as a luggage storage space. The vehicle seat includes: a support leg (6A, 6B, 6C) to support weight related to a seat cushion (2); a leg holding member (8) to hold a lower part (6C) of the support leg (6A, 6B, 6C); and a slide mechanism (18A, 18B) to move the seat cushion (2) and a seat back (3) in a front/back direction. The seat has a tip-up function to rotate the seat cushion (2) so that its front part is in a higher position than its rear part and the seating surface of the seat cushion (2) and the front surface of the seat back (3) face each other, in which the leg holding member (8) is located at a part (18A) of the slide mechanism (18A, 18B) which moves along with the seat cushion (2) and the seat back (3).

A seat trim cover management system for seat cushion length adjustment includes a seat cushion base having stationary portion and an adjustable portion wherein the stationary portion and the adjustable portion include a horizontal top surface and a vertical front surface. An adjustment mechanism is in mechanical communication with the stationary portion and the adjustable portion and is configured to manipulate the adjustable portion. A cover material includes a first end attached to the horizontal top surface of the stationary portion or the adjustable portion, and at least one seat cover management system is attached to a second end of the cover material and is configured to maintain tension between the first end and second end of the cover material while the cover material shrouds the gap created between the stationary portion and the adjustable portion when at the extended position.

Provided is a seat frame for a saddled vehicle capable of increasing the coupling rigidity at the separable rear end and having aesthetic aspect. A seat frame of a vehicle body frame includes a front part fixed to the vehicle body frame and a rear part that can be disconnected from the front part, the front part and the rear part being separated at a rear part of the vehicle body. The front part and the rear part are fixed with a fastening member that engages from the inside of the vehicle width direction. The front part has a hollow rear end, and the rear part includes a solid engagement part at the front end. The fastening member as a bolt penetrates through the lateral wall at the rear end to be screwed with the engagement part inserted into the rear end. The rear part includes the engagement part and a pipe member to be connected to a rear part of the engagement part.

Improvement is made in a configuration of a movable portion movable to adjust a length of a seat cushion. A vehicle seat includes a seat cushion having a fixed portion and a movable portion movable relative to the fixed portion for adjustment of a length of the seat cushion, and also includes a notch arranged on the movable portion as a movable portion side engagement portion and an engagement plate piece arranged on the fixed portion as a fixed portion side engagement portion. The engagement plate piece is movable between i) a locking position engaged with the notch to bring the movable portion into an unmovable state, and ii) an unlocking position released from the notch to bring the movable portion into a movable state. The movable portion includes a pressing wire to move the engagement plate piece from the locking position to the unlocking position.

Provided is to stabilize a fixed state of each bag body provided at a vehicle seat and configured to expand to push a corresponding one of the shoulders of a seated passenger. Of a seat back provided at the vehicle seat, each shoulder support configured to support a corresponding one of the shoulders of the seated passenger includes an air cell configured to expand by injection of air. The air cell includes protrusions extending in a predetermined direction and provided at respective end portions of the air bag in the extending direction thereof. The air cell is attached to the inside of the seat back in such a manner that each of the protrusions provided at respective end portions in the extending direction is fixed to a corresponding one of fixing positions separated from each other in the width direction of the vehicle seat.

A seat cushion adjuster in one aspect of the present disclosure comprises at least one bracket, at least one slider, at least one first interposing member, and at least one second interposing member. The slider is inserted into an inner hollow portion of the bracket. The slider comprises a base plate part of a plate shape and a pair of raised parts. The pair of raised parts is raised from a pair of ends of the base plate part so as to be raised with respect to one surface of the base plate part. The first interposing member is disposed between an inner wall of the bracket and the slider. The second interposing member is disposed between the inner wall of the bracket and the slider so as to face the first interposing member.

An adjustable vehicle seat includes a seat base having a seat surface and a backrest having a backrest surface. In the seat base and/or in the backrest, sensors are provided that detect forces, pressures and/or movements effected by a person sitting on the vehicle seat and consequently issue a signal. A control device is provided that detects the signals issued by the sensors and actuates actuators provided in the vehicle seat to adjust the seat base and/or backrest, or components thereof, in order to adjust the vehicle seat.

A seat includes a cushion comprising a foam body and a trim cover disposed thereon, the trim cover having a forward portion at a front of the cushion and at least one elastic band attached to the forward portion; and a movable cushion length adjuster having an extended position and a retracted position, the movable length adjuster comprising a body with an occupant surface on a first side, and features on a second side, opposite to the first side. The at least one elastic band is routed on the features, and in the retracted position, the movable cushion length adjuster at least partially covers a portion of the cushion, and in the extended position, the length adjuster is spaced apart from the portion such that the at least one elastic band tensions the trim cover by pulling on the forward portion.
