Car backseat tray table mechanical assembly

  • To use these pictures first read previous post and refer below pictures to assemble car seat table.


car seat frame

once you open leather cover of seat you will find this kind of metal strips or metal rods . you will add two rods or one sheet to give tray system mechanical support as given below
mechanical support for base
Attach two rods as in above diagram. you can use metal strips or a metal sheet between frame to provide mechanical support to base of car seat tray
base of car back seat table
Next step is to attach base.
To do this drill four holes in previously attached rods making a square . reapply leather cover and drill four holes in the base of car tray base both should in front of each other

Then drill small holes keeping in mind that upper two should outwards from center and lower two should inwards and then insert four small cylinders which will act as joints(axis of rotation) for top of table tray system

Drill two more holes in the sides of top of car tray system having same size as of cylinders . so that top can merely rotate around cylinders.
at distance such that small area rotate inside base (will be used later to read position)
top joint of car backseat table
Repeat same process to make two other joints by adding two more cylinders to support table top or open/close levers as shown in above pictures

open/close levers of car backseat table
Now final step is to attach two metal strips acting as open/close levers  .
Drill two holes of size slightly more than cylinders on one side of each step and on the other sides drill holes size of a rivet .
insert one strip on lower cylinder and other hole on the cylinders on the car tray table .Place other two holes in front of each other and attach with a rivet . repeat the process on the other side too.

Manual car backseat tray table is assembled .design of table top is left to user specifications
(next post will be about automatic car backseat tray table)

Car backseat table

By
Having your lunch or a light meal while you are travelling is a trouble for every one. Some of luxurious cars are now including tables for passengers on backseats. One approach to have this facility is to design your own using simple steps and parts 1st of all you need to make table top for which you can use kitchen cutting board as table top or you can machine your own . Modify it upto your requirements like cup holding place etc Next you have to plan attachement to the seats. It depends on the type of seats you have. Here i can write some of possibillities like if car seats have cloth on back then you have to open cover and attach rods horizontally to the frame of seat and if seats came with plastic on back then system's base could be attached with screws directly. base will also provide mechanichal support. Next step is to dicide about working of system. Some of options are Manual. Single table operating with button. Centralized system controlled by one keypad or remote...

Car Backseat Table System using PIC Micro-controller

By

Before installing micro controller to operate car backseat table read previous posts about how to install mechanical parts, installing dc motor and position sensors First of all select any  micro-controller   which is available and have external interrupts. I am using PIC-16f1789 in car backseat tray table Identify signals to operate the system To operate Car back seat table using micro-controller we need 3 signals for each table. One signal from open and close command to each table Detect open position of each table Detect close position of each table Here we are operating two tables so we need total six signals which are connected to port A through current limiting resistors(value of which depends on device type, specified on datasheet of I.C. you  are using). Electrical specifications for PIC 16f1789 Port A is used for interrupt input.Connections will be as follows. port A,1 connect with open/close button for table 1. port A,2 connect with...
