Seat recliner mechanism.
There are two types of seat recliner mechanism. The first type is called a power seat recliner. The second type is called an automatic seat recliner.
Seat reclining mechanism for an automobile of this kind that allows forward folding of both the seat pan and the seat recliner mechanism 10 allows the fully reclined positions of both the seat pan and the seat recliner mechanism. In one model of seat recliner mechanism, an upper pivot rod is provided with a straight toothed crank that meshes with a rotary reclining gear. The seat recliner mechanism 10 further includes a lower pivot rod and footrest that allow the lower portion of the seat to be reclined. A roller bearing, which is mounted on an upper side of the seat pan, rotates on a hinge portion that is located on the inside surface of the seat pan.
An example of a power seat recliner mechanism includes the model called U-Box. This model has a seat recliner mechanism that is powered by a twenty-eight volt motor. It consists of three major components, namely, upper and lower recline adjustment mechanisms, and a footrest. The seat recline angle can be controlled in a number of ways using the upper and lower recline adjustment mechanisms. The seat back also has some support pouches. These are located at the bottom of the seat in front of each of the lower and upper seat recline positioning bolts.
In some examples, there is another rotatable seat recliner mechanism that has a swing arm mechanism. Such a mechanism may have as many as nine arm positions. The seatback can be moved up or down in relation to the angle of the seat. In addition, this type of mechanism can move the seat forward or backward in relation to the seatback angle. The seat forward and back moving mechanisms can move the seat forward or backward in accordance with the angle of the seat, while the footrest can be moved up or down in relation to the angle of the seat.
The seat recliner mechanism can further comprise upper and lower door, lower and upper platform, and frame mechanisms, among others. All such features can contribute to the well-being of the user. There are some important points to consider when selecting such devices, namely that the mechanism must provide for the safe operation and performance of all its parts, it must be reliable and robust, it must provide for the safe positioning of the user in all circumstances, and it must support the natural movements of the user.
The seat recliner mechanism provides for safe and reliable operation of all its parts and is robust and durable. The seat back can be positioned in any direction in accordance with the seat recliner mechanism 10, which allows for the adjustment of the angles of recline according to the users’ needs. In addition, this mechanism has been found to provide for the proper alignment of the head and neck during locomotion.
The seat recliner mechanism further comprises a rotatable and a fixed rod with a hinge so that the seatback can be easily moved in all directions. There is a spring mechanism that assists in the easy movement of the seat back in its reclining position, and a motor-driven mechanism that pushes the rod in the direction of the users’ choice. The motor can be operated by a remote control. The seat reclining mechanism further comprises a seat cushion on a frame that is centrally attached to the upper frame.
The seat recliner mechanism includes a hand crank arm that has an attachment with a screw threaded at its end to engage a seat cushion. The weight of this seat cushion helps in holding the seat in the desired reclining position when the user is not sitting on it, and also facilitates easy steering in the direction of one’s choice while driving. There is also a movable top rail attached to the uppermost end of this frame, and a motor-driven bottom rail that is screwed into a slightly curved rail at the bottom of this frame. This bottom rail allows for easy attachment of foot rests, and a tilting mechanism that tilt the seat forward and backwards in keeping with the change in the direction of travel. The frame also acts as a footrest.
The leg rest, which can be slightly protruding or otherwise shaped, is designed to support the foot while the user is sitting on it. The uppermost end of this leg rest is fitted with an adjustment lever that can be used to either extend or shorten the leg rest, so as to suit the height of a particular user. The seat recliner mechanism in a folded forward position is similar to that in a fully deployed position, and this can be clearly seen in the illustration. The leg rest could be extended or shortened as and when necessary.
One other feature is described wherein a spring connected to one side of said seat recliner mechanism is fixed to said upper frame member. This spring helps to keep said upper frame member in a bent upward position when the seat recline mechanism is being used. The upper frame member, when moving in an upright position, acts upon the spring and helps to make the said spring rigid thereby helping the lower frame member to assume a position similar to that of its free end. This helps to make the seat recliner mechanism lock into position after each use.
In order to describe further the process by which this invention is practiced, it is hoped that the following description will be helpful in the understanding of what is meant by each of its various stages. The first stage is that the seat recliner mechanism is placed in a fully deployed position in which the seat back is at its lowest position. The second stage is that the seat recliner mechanism is placed in a fully deployed position but is left in an open position in which it forms an arc with said opening.
