In the automotive sector, doors have an important issue in terms of vehicle and passenger safety. Therefore, different kinds of materials and mechanisms have been being designed and parameters have been being investigated and analyzed in order to increase the functional efficiency of the vehicle doors. In this study, an automatic open/close mechanism is designed which can be used in all types of vehicles with sliding doors. Sliding door mechanism with rope system was analyzed and information about the parts of the mechanism was explained. Door weight, rope diameter, torque, opening time of the door parameters were examined. Finally, the designed mechanism has mounted to a vehicle and it has been observed to work successfully.

In daily life, most of the devices, machines and furniture, which we use in our homes and make our life easier, have many different opening and closing systems. Some criteria may be required for the opening/closing shape of systems. For example, in some systems, it may be desirable that opened part uses minimum volume, facilitates daily life, or the system is balanced in each opening position. Those type of opening and closing systems are widely used sofa beds, seats and bed bases in the furniture sector. Many opening/closing systems have various locking mechanisms which are used to ensure opened final position or in some cases it is held in the final position by the force of the human arm. In this study, a kinematic analysis was carried out to design a base mechanism which could be stabilized at every position instead of the final position, and a virtual prototype was made.

Today, the works that improve ergonomics and human comfort in the furniture sector are consistently increasing. In addition to this, improving the current situation of the mechanism systems, which are used in the widely produced seating and bed groups, is gaining momentum every day. The design of the mechanisms that provide the desired function is considered within the kinematic synthesis of the mechanisms. The kinematic synthesis of mechanisms is examined in three main categories as function, trajectory and motion synthesis. It is expected that while following the desired trajectory the configuration of the mechanical systems, throughout their movement as well as their area-volume usage will be optimum. Thanks to the mechanisms that provide these requirements, quality of the machine, tools, etc. will increase. In this study, in order to improve the opening and closing systems used in the furniture sector, a mechanism system has been designed and virtual prototypes have been realized in order to ensure optimum use of area and volume during the movement of these parts.
