A pair of latch members 36R, 36L in a case 20C protrudes from an outer face of the case 20C by a spring 38 and when the case 20C is passed through a wall hole 22H, the latch members 36R, 36L are narrowed by an engagement between outer edge (guiding) slant face 36ROI, 36LOI and a wall hole 22H and after the case 20C has passed through the wall hole 22H, the latch members 36R, 36L are spread by a spring 38 so as to engage the engagement slant faces 36RLI, 36LLI with the wall hole 22H and also while fixing temporarily the case 22C to the wall 22 together with a flange 20FL of the case 22C. After that, a screw 32 is screwed to draw the nut 34 toward the flange 20FL and to engage securely the latch members 36R, 36L held to the nut 34 with the wall hole 22H to complete secure fixing of the case 20C.

An auxiliary member attachment structure for a vehicle seat. The auxiliary member attachment structure includes an auxiliary member at an outer side of the vehicle seat. The vehicle seat has a seat cushion that is capable of transitioning from a seating position to a storage position aligned with a seat back. The auxiliary member being rotatable, about a shaft in the vehicle seat extending along the seat width direction, between a reference position at which the auxiliary member is upright and a holding position at which the auxiliary member is rotated closer to a front side of a vehicle. The auxiliary member attachment structure further includes a rotation restriction unit configured to restrict rotation of the auxiliary member at the reference position when the seat cushion is at the seating position, and cease the restriction of rotation of the auxiliary member when the seat cushion is at the storage position.

The present invention is related to a new passenger seat which is developed for the commercial vehicles and rail systems that are used in the passenger transport. Said passenger seat comprises: a massage pad for increasing the ergonomics in the waist section of the passenger and applying massage; a compressor for inflating the massage pad by means of filling it with air; cooling pads for cooling the passenger; a heating pad for heating the upper portion of the seat and the backrest contacting the passenger; a presence sensor for determining whether there is a passenger on the passenger seat or not; a belt sensor for determining whether the passenger sitting on the passenger seat fastens the safety belt or not; a wireless charging unit which allows the passenger to charge his/her mobile device without using a connection cable; a manual control panel which allows the passenger to control the heating pad, cooling pad and the massage pad; a wireless connection module which allows the passenger to control the heating pad, cooling pad and the massage pad through his/her mobile device; an identification label for identifying the passenger seat to the application downloaded to the mobile device of the passenger; a control unit where the data collected from the presence sensor and belt sensor are transmitted. A system for using data obtained from a passenger seat in a commercial vehicle or a rail system in passenger traffic is also provided.

A passenger seat assembly includes a seat support and an immobile seat shell mounted on the seat support. The seat shell can include a bench and a backrest. The bench includes a forward edge, an aft edge, and a top surface extending between the forward edge and the aft edge. The backrest can be connected to the aft edge of the bench and can extend in an upward direction from the top surface of the bench. In some cases, the backrest includes an upright portion connected to the bench and angled at a first angle with respect to the top surface of the bench, and a resting portion connected to the bench and angled at a second angle with respect to the top surface of the bench.

A vehicle seat includes a seat frame including a pan frame (12), a blower, and a bracket (50) configured to attach the blower to the pan frame (12). The bracket (50) is provided with a first engagement portion (110) protruding toward the pan frame (12), and the pan frame (12) is provided with a first engagement hole (12A) in which the first engagement portion (110) is engageable. The first engagement portion (110) includes a first stopper portion (112) configured to be locked to the pan frame (12) when the first engagement portion (110) is engaged in the first engagement hole (12A), and a first elastically deformable portion (113) configured to deform elastically to allow the first stopper portion (112) to pass through the first engagement hole (12A) when the first engagement portion (110) is inserted into the first engagement hole (12A).

The present invention relates to a seat (20), in particular for a vehicle, comprising a first sensor (32) arranged in order to generate a first electrical signal upon a user seating themselves on a seat (20) and upon the vacating of the seat (20) by the user. The seat (20) also comprises a second sensor (34) that is capable of generating a second electrical signal in a substantially continuous or repeated manner when the user is seated on the seat (20).

The invention relates to a vehicle (10) seat (22), comprising: a seat bottom (26); a backrest (28) secured to the seat bottom (26), and at least one leg (32) supporting the seat bottom (26).

The leg (32) comprises at least three segments (44, 46, 48), including: a first segment (44) fastened to the lower face (40) of the seat bottom (26), a second segment (46) fastened to the floor (20, 21) of the vehicle (10), and a third segment (48) joining the first segment (44) and the second segment (46).
The third segment (48) is arranged so that the leg (32) defines a housing (50) between the seat bottom (26) and the floor (20, 21).

The housing (50) is able to accommodate at least one piece of carry-on luggage (52) such that it does not protrude by more than 100 mm from the front edge (34) or the rear edge (36) of the seat bottom (26).
