Description
-1 DEFINITION A NEW FOOTREST DESIGN FOR BUS SEATS. Technical Area The present invention relates to footrests for bus seats. The invention relates specifically to a novel footrest structure for bus seats that can be added to all bus seats for passenger comfort during long bus journeys, operating based on user power, thus eliminating the need to calculate and test the on / off cycle time. State of the Art Vehicle seats are known to have footrests. The footrest plate is positioned axially at the end of the seat cushion and is operated by an electric motor. Footrests on bus seats, due to their current design, have a limited service life. After a certain period, the mechanism becomes inoperable. Because of their limited lifespan, they require replacement over time. The high production costs of existing footrests have created a need to develop longer-lasting technical solutions at lower costs. Korean patent application number KR101470218 relates to a seat cushion extension adapter for the rear seat of a vehicle, designed to provide a leg rest function and a foot rest function to enhance user comfort. The seat cushion extension kit includes a pair of legrest guide modules designed for sliding back and forth, attached to a movable rail that forms a seat track; it also transmits leg force to the guide modules simultaneously. The system includes a legrest drive module connected to legrest guide modules to transmit the -2 force; and a legrest plate connected to legrest modules in front of the legrest module. It's an integrated design within the seat, and the opening system is a completely different structure. However, this application has several drawbacks, including high production costs, a lack of durability, and the need to calculate and test the on / off cycle time. New technical developments are needed to overcome these problems. Explanation of the Purposes of the Invention Based on the current state of the art, the aim of this invention is to develop a new footrest for bus seats that overcomes the shortcomings of existing designs and operates based on user force. Another objective of the invention is to develop a footrest structure that can be variably adjusted in distance from the seat cushion to meet the appropriate needs of passengers. Another aim of the invention is to create a more cost-effective footrest. Another aim of the invention is to develop a footrest that does not require calculating and testing the on-off cycle time. Another objective of the invention is to develop a footrest that can be added to all bus seats, operating based on user force and usable without the need for testing. To achieve the aforementioned objectives, it can be added to all bus seats, operates based on user power, and therefore reduces the on / off cycle time. -3 A new footrest structure has been developed for bus seats that does not require calculation and testing. Explaining the Figures Figure 1 shows a drawing of the closed view of the mechanism behind the seat, in a representative application of the invention. Figure 2 shows a representative application of the invention, depicting the closed and open positions under the armpit indicated by an arrow. Figure 3 shows a diagram illustrating the closed and open modes of operation of the mechanism in a representative application of the invention. Reference Numbers 1 Footrest 5 Guide arm 2 Profile 6 Bracket 3 Telescopic element 7 Body 4 Movable arm Detailed Description of the Invention The invention is a new footrest (1) mechanism for bus seats and brings many advantages. A metal tubular footrest (1) is formed on the mechanism housing (7) for attachment to the vehicle seat. A metal tubular profile (2) is welded to the footrest. The profile (2) slides back and forth inside the tubular telescopic element (3). Its position is adjusted according to the passenger's wishes. The nested tubular telescopic element (3) is welded onto a metal tubular guide arm (5). The bracket (6) rotates around the guide arm (5). This rotational movement helps to move the mechanism according to the passenger's wishes. -4 The movable lever (4) is used to allow the passenger to make adjustments independently. Thanks to the movable lever (4) on the telescopic element (3), adjustment can be made by moving back and forth from the adjustment points on the profile (2). This design has no lifespan because it relies entirely on human labor. Furthermore, because it is constructed using metal pipes, it is significantly less expensive than other designs. Thanks to the developed mechanism, it can be added to all bus seats for the comfort of passengers on long bus journeys. Its most important feature is that it relies on user power. Therefore, it is not necessary to calculate and test the opening-closing cycle time. According to the invention, a guide arm (6) includes an angled profile (2) with one end axially attached to the wing of the profile (2), so that the other end of the guide arm (6) is axially attached to one end. The footrest (1) fixed to the floor has a mechanism developed which has fixing devices by which the arrangement oriented in the longitudinal direction of the vehicle can be released in the desired position and thus the profile (2) forms the footrest area. The invention relates to the footrest mechanisms of bus seats and is characterized by having a user-powered mechanism body (7) that can be added to all bus seats for the comfort of passengers on long bus journeys, and an integrated footrest (1) that can be automatically adjusted according to the foot length, with elements that enable the rotational movement of the extension which is nested back and forth inside the mechanism body (7) and has adjustment points on it. The mechanism housing (7) contains a telescopic element (3) connected to the footrest (1), a profile (2) that moves back and forth, a guide arm (5) on the telescopic element (3), and a bracket (6) that enables the rotational movement of the guide arm (5). -5It includes a metal tube footrest (1), a metal tube profile (2) welded perpendicular to the footrest, a movable arm (4) that allows adjustment according to the foot length from the adjustment points on the profile (2), a metal tube telescopic element (3) through which the profile (2) moves and passes, a guide arm (5) welded to the telescopic element (3), and a bracket (6) that allows the forward movement of the guide arm (5) to be converted into rotational movement. The guide arm (6) includes a footrest (1) connected to an angled profile ίο (2) with one end attached axially to the wing of the profile (2) so that the other end of the guide arm (6) is attached axially to one end. The footrest (1) mechanism 15 includes fixing devices which can be released in the desired position, and thus the profile (2) forms the footrest area, which is fixed to the ground.
