RU96840U1 - CHAIR CONTROL PANEL VEHICLE - Google Patents

Abstract

The utility model relates to signaling devices of calls received from passengers, and can be used in passenger transport, where a remote call for maintenance personnel is provided. A distinctive feature of the proposed design is that the chair control panel, comprising a housing with fastening elements to the armrest housing of the chair and, interconnected, a master body made in the form of a keyboard, an executive body and a command line, is equipped with a device for preventing the formation of a false control signal in the command line. The device for preventing the formation of a false control signal in the command line in one case can be made in the form of mechanical locking of the master body with the mutual spatial movement of the keyboard and armrest body, in the other case as an element for initiating the operating mode of the executive body. The implementation of the claimed utility model will improve flight safety and operational reliability of the flight attendant call system.

Description

The utility model relates to signaling devices of calls received from passengers, and can be used in passenger transport, where a remote call for maintenance personnel is provided.

Known seat control panel of an aircraft selected as a prototype [1], comprising a housing with fastening elements to the armrest housing of the chair and, interconnected, a master body made in the form of a keyboard, an executive body and a command line.

The disadvantage of this device is that the keyboard of the chair console does not have protection against false alarms. In a known design, the keyboard of the master is located on top of the armrest of the passenger seat. At the time of boarding, leaving the seat or while in the seat during the flight, the passenger can, by accidentally pressing a button on the keyboard, generate a control signal that, after passing through the command line, will make a fake call to the flight attendant or issue a false command to control the devices. This complicates the work of the maintenance staff, which is unacceptable in critical situations.

The problem the utility model aims to solve is to eliminate this drawback, namely, to eliminate the false control signal to the command line and, thereby, increase the operational reliability of the flight attendant call system and increase flight safety.

The inventive utility model, as well as the device selected as a prototype, contains a housing with fastening elements to the armrest housing of the chair and, interconnected, a master body made in the form of a keyboard, an executive body and a command line, but, unlike the prototype, a chair the control panel is equipped with a device for preventing the formation of a false control signal in the command line.

The goal is also achieved by the fact that the device for preventing the formation of a false control signal in the command line is made in the form of mechanical locking of the master unit with the mutual spatial movement of the keyboard and armrest body.

The problem is solved by the fact that the device for preventing the formation of a false control signal in the command line is made in the form of an element for initiating the operating mode of the executive body.

Figure 1 shows a diagram of a specific implementation of the claimed device: a) an end view of the armrest; b) a top view in section along the line AA.

In this particular case, the seat control panel of an aircraft consists of a housing 1, a keyboard 2, a command line 3. The armrest housing of a passenger seat 4 is shown in section. In Fig.1 b) the seat control panel is extended from the armrest of the passenger seat.

The inventive device operates as follows. When the chair console is connected to the flight attendant call device using command line 3, keyboard 2 is activated. In the initial state, the housing 1 is pushed into the armrest housing 4 and the upper wall of the armrest housing 4 closes the keyboard 2. To signal the flight attendant or control signals, the chair console extends from the armrest housing 4, thereby accessing the keyboard 2, with the help of which the desired actions. Thus, in order to make a call to the flight attendant it is necessary to perform an additional operation - to extend the chair control panel. In this particular case, the device for preventing the formation of a false control signal in the command line is implemented in the form of a mechanical locking of the master (keyboard), which is based on the mutual spatial movement of the keyboard and armrest body.

Figure 2 shows a diagram of a specific implementation, where the device for preventing the formation of a random control signal in the command line is made in the form of an additional keyboard button that is electrically connected to the command line and with which the keyboard unlock signal is sent.

Here - 1 - body, 2 - keyboard, 3 - command line, 4 - armrest housing, 5 - keypad lock button.

The proposed device operates as follows. Initially, the keyboard is disconnected from the command line, after pressing the key lock button 5, the keyboard 2 is connected to the command line 3 and the chair control panel enters the operating state. Thus, in order to make a call to the flight attendant or give a control signal, it is necessary to perform two actions in a certain sequence, thereby connecting the actuator to the command line. In this embodiment, the device for preventing the formation of a false control signal in the command line is an element for initiating the operating mode of the executive body, made in the form of an additional keyboard button electrically connected to the command line.

The inventive device relates to one of the components of the signal devices of aircraft, which are subject to increased requirements for the intended purpose, especially in various critical situations.

The industrial applicability of the proposed solution is confirmed by the possibility of its multiple reproduction in the manufacturing process.

The chair control panel, in accordance with the stated solution, is designed for serial production using standard equipment, modern technologies and equipment.
