Definitions

• the subject of the invention is a mass transit vehicle chair, to be used in buses, vans and other mass transit vehicles requiring the folding of both single and double chairs in parallel to the sidewall of the vehicle.
• This solution is labour absorbing and requires the storage of removed chairs outside of the vehicle.
• the chair frame is mounted rotating on a bolt and supported on a bracket on a retainer.
• the frame bracket is permanently connected to a retainer in a manner that allows for separating it.
• the chair should be rotated on a complex set of supports, which form the kinematic system of this mechanism. This requires significant physical effort. Besides, after placing the chairs vertically, on the outside the visible chair mechanisms remain, which may negatively affect the passengers, for example damaging their clothes or cuts.
• the problem is carrying a wheelchair into the vehicle.
• a lift is installed, which enables the raising of an occupied wheelchair to the level of the vehicle floor and further on, moving the wheelchair inside, to a previously prepared place.
• space in the bus is required in order to be able to move the wheelchair around.
• a chair or a set of chairs may not be mounted to the wall.
• two seating spaces for passengers are removed, which causes a loss for the carrier.
• the essence of the invention which is a mass transit vehicle chair with a frame mounted seat and backrest, consists of a seat frame mounted rotationally on a bolt which is mounted rotationally on the vehicle floor and side structure, on a retaining bolt, and on a retainer bolt, mounted rotationally on a bolt, which is placed on the vehicle side structure or on a vertical support, also the backrest is placed on an articulated joint with a 135° freedom of movement.
• the side structure is the vehicle sidewall.
• the side structure is the frame structure of vehicle doors, in the zone of which the lift is located.
• the external surface is a highly aesthetic external wall of the backrest covering the sharp components of the mounting mechanism
• the subject of the invention in a sample implementation was shown in a view, where on fig. 1 the chair is presented in a horizontal projection onto a vertical plane from the front in the operational position, on fig. 2 the chair is presented in a horizontal projection onto a vertical plane from the side in the operational position, on fig. 3 the mounting and rotation mechanism of the chair is presented, on fig. 4 the mounting support is presented, on fig. 5 the chair is presented in the movement phase, on fig. 6 the chair is presented mounted on the doors of a vehicle in an operational position, on fig. 7 the chair is presented mounted on the doors of a vehicle in a folded position, and on fig. 8 the chair is presented folded when the vehicle doors are open.
• the frame 2 is mounted on one side rotationaliy on bolt 3 on support 4.
• the opposite end of the support 4 is mounted rotationaliy on the bolt 5 in the lower zone of the support 6, mounted on the vehicle sidewall.
• the bolt 3 is placed near the chair centre of gravity.
• Frame 2 is also mounted rotationaliy on the bolt 7 of the support 8.
• the opposite end of the support 8 is mounted on the bolt 9 in the upper zone of the support 6.
• the backrest 10 of the chair is mounted rotationaliy on the bolt JJ_, which can incline in relation to the seat I by a 135° angle.
• the seat has a headrest J_2 placed on an articulated joint 13, which allows the headrest ⁇ 2 to rotate forward by a 90° angle.
• the chair For the stabilisation of reciprocal locations, the chair has a support 8 and frame 2 movement lock and in the backrest J_0 rotation articulated joint 1 1 zone has a backrest 10 inclination lock, not shown on the drawing.
• the headrests J_2 are set approximately in parallel to the seat L
• the backrest K is unlocked and folded approximately parallel to the seat 1.
• Headrest ⁇ 2 is located in the space between the seat and the backrest of the previous chair.
• the support 4 is then unlocked and by pressing the front zone of the chair the supports 4 and 8 rotate around the bolts and raise the external zone of the chairs upwards, until an approximately vertical position is obtained.
• a special case of this solution is a chair mounted on the vehicle doors, in order to enable entrance of a wheelchair by a lift J_5 located within the zone of the doors 14.
• Vertical support 6 of the mounting of the frame 2 bolt 5, 9 is mounted on a frame structure of the doors 14, in the zone of which the lift J_5 is mounted, and on the lower lock, located on the floor 16 in the zone of the doors 14.
• the chair located in the zone of the doors j_4 at the lift j_5 is unfolded and its seats 1 have an approximately horizontal position, and the backrests 10 approximately vertical.
• the chair In the case when it is necessary to use the doors in order to start the lift and enter a wheelchair into the vehicle, not shown on the drawing, the chair is folded so that the headrests J_2 are set approximately parallel to the seat 1. Then the backrest ⁇ ) is unlocked and folded approximately parallel to the seats 1. Then the chair is rotated in the known manner on the supports in order to obtain a position next to the wall.
• the doors J_4 are closed. Depending on needs, the chair will be left in a closed or open position.
