A seat gap guarding apparatus is disclosed. In embodiments, the seat gap guarding apparatus includes a support member configured to be coupled to a repositionable seat and one or more deformable guard members fixed to the support member. The one or more deformable guard members are configured to press against a surface adjacent to the repositionable seat to keep objects and/or debris from falling into the gap between the repositionable seat and the surface adjacent to the repositionable seat. When the repositionable seat is transitioned from a first position to a second position, the support member is configured to maintain the one or more deformable guard members pressed against the surface adjacent to the repositionable seat.

Described are torque bearing assemblies for passenger seats. A torque bearing attachment (122, 222, 322, 422) includes an elongated body having a forward edge configured to mate with an aft end (140) of a seat bottom pan (120), and first and second side edges having attachment elements (136) for connecting the assembly with a passenger seat frame (108). The first and second side edges can be positioned orthogonal to the forward edge and at opposite ends of the elongated body with respect to each other.

A method of method of manufacturing an upholstered chair for a mass transit vehicle includes forming a seat insert and a backrest insert, injection molding a layer of upholstery having enveloping flanges and beads at a periphery thereof, placing the upholstery onto the seat and backrest inserts such that the flanges and beads engage with an underside of the inserts, and attaching the seat insert and the backrest insert onto a chair frame. The flanges and beads secure the upholstery to the seat and backrest insert.

A seat support mechanism including a leg pedestal (11), which is fixedly provided on a floor in the vicinity of a side wall (A), a moving pedestal (20), which is disposed under a top face part (12) of the leg pedestal (11) and is capable of being advanced/retracted in a direction orthogonal to the side wall A; an underframe (30) of the seat, which is disposed above the top face part (12) of the leg pedestal (11), and is turnably supported by a turning shaft (41) in the moving pedestal (20), the turning shaft (41) avoiding an interference with the top face part (12), and an interlocking mechanism (50), which interlocks turning and advancing/retracting of the underframe (30), in which, when the seat is turned together with the underframe (30), the interlocking mechanism (50) converts the turning motion of the underframe (30) into a linear motion and, through the turning shaft (41), transmits it to the moving pedestal (20), thereby causing the moving pedestal (20) and the underframe (30) to be advanced/retracted in a direction orthogonal to the side wall (A).

A vehicle seat, in particular a passenger seat for a bus, includes a seat member with a seat upholstery carrier and seat upholstery, which is rigidly arranged on the seat upholstery carrier; the vehicle seat also includes a backrest with a back upholstery carrier and back upholstery, which is rigidly arranged on the back upholstery carrier; and a support structure for receiving forces which act on the vehicle seat. The support structure is constructed as a rigid carrier frame arranged at the peripheral side outside the seat member and the backrest and which is connected to the seat upholstery carrier and the back upholstery carrier. The carrier frame has carrier rails which are arranged in pairs and which extend along opposing lateral edges of the seat member and the backrest.

According to an illustrative embodiment of the present disclosure, there is provided a vehicle seat including: a seat cushion that serves as a seating portion which receives a load of an occupant; an ottoman that is connected to a front portion of the seat cushion; a base that supports the seat cushion from a vehicle floor in a seating position at which the seat cushion receives the occupant and in a tip-up position at which the seat cushion is tipped up rearward from the seating position; and a folding mechanism that moves the ottoman between an initial position at which the ottoman is positioned at the front portion of the seat cushion and a folding position at which the ottoman is retracted beneath the seat cushion in accordance with a movement of the seat cushion from the seating position and the tip-up position.

The invention relates to a vehicle seat for simultaneous adjustment of a seat depth and a lumbar support of the vehicle seat, wherein the vehicle seat comprises a backrest frame, a seat part frame and a connecting frame, wherein the connecting frame is rotatably connected about a first rotation axis to the backrest frame and rotatably connected about a second rotation axis to the seat part frame and connects the seat part frame to the backrest frame, wherein the seat part frame and the backrest frame are connected to a supporting element such that the seat part frame and the backrest frame are simultaneously displaceable relative to the supporting element.

A seating group comprising a first seat and a second seat arranged side by side and each adjustable in seat depth and lumbar support, each comprising a seat part and a backrest part. It may be provided that the first seat and the second seat are each formed and provided for simultaneous adjustment of a seat depth and a lumbar support, wherein the seating group is formed such that the first seat and the second seat are adjustable independently of each other in the respective seat depth and lumbar support.

A seat for a multi-passenger vehicle. The seat includes a seat cushion mounted on a frame of the seat, a back cushion mounted to the frame, and a seat back mounted on an opposite side of the frame. The back cushion and the seat back extend transversely away from the seat cushion. The seat back includes a head impact portion and a leg impact portion. The leg impact portion includes expanded polyethylene (EPE) foam having a second density between 1.0 and 1.6 pcf.

Lightweight passenger seats that are especially adapted for use in aircraft cabins. The seats will include a seat back and a seat bottom having a basin which defines a recessed central interior space, a plurality of straps having opposed ends connected to respective upper edge regions of the basin so as to be positioned under tension over the recessed central interior space; and a cover cushion covering the straps and connected to the basin. The seat back may be connected at opposed sides thereof to upright support members adjacent a lumbar region thereof so as to establish an upper region of the seat back above the lumbar region which is capable of being resiliently flexed between upright and rearwardly inclined positions.
