Headrest retention device for vehicles
The present invention relates to a retention device for head restraints of vehicles, in particular for head restraints of cars, and which can be released to regulate the height of the head restraint by actuating a push button. Background of the invention
10 For safety reasons, vehicle seats include a head restraint, which in the event of an accident, serves as protection to prevent backward movement of the head.
In order to fulfill its safety function, the head restraints must be able to be
15 adjustable in height, to adapt to the height of the seat user, and this regulation must be simple and safe.
At present, to allow this regulation, the head restraints comprise a pair of fixing rods that are housed inside the seat back, in particular in the
20 inside the guide elements that are placed in the seat back.
These guide elements comprise a retention element that can move from a retention position, in which the retention element is housed in a notch made in the fixing rod, preventing the movement of the fixing rod with respect to the
25 guide element, to a release position, in which the fixing rod can move relative to the guide element to regulate the height of the headrest.
This regulation is carried out by pressing a button, which allows said retention element to be moved from its retention position to its release position.
30 In most guides the retention is located at the same level as the actuation mechanism located outside the seat structure. In other cases the retention is located within the structure of the seat, so that it is necessary to incorporate, apart from the retention and actuation elements, a mechanism capable of transmitting the movement
35 between the parts, thus increasing the amount of necessary components, assembly and manufacturing costs.

01-23-2014 Description of the invention
With the head restraint device for vehicles of the invention, the aforementioned drawbacks are resolved, presenting other advantages that will be described below.
The head restraint device for vehicles according to the present invention comprises:
10 -a guide element inside which a headrest fixing rod can be housed;
- a retention element movable between a retention position, in which it avoids the
15 displacement of said fixing rod with respect to said guide element, and a release position, in which it allows the movement of said fixing rod with respect to said guide element;
- a push button to move said retention element from said retention position 20 to said release position;
- at least one lever linked to said push button that transfers the movement of said push button to the retention element, which may be located at a different level; Y
25 - an elastic element, which presses said lever towards the retention position of said retention element,
and characterized in that said retention element and said lever are in one piece.
According to a preferred embodiment, said retention element and said lever are formed from a rod.
Preferably, said rod is U-shaped, the lower part of which is the retention element and its arms are levers. 35 In addition, the or each lever is preferably formed by two straight sections which
P201430063
01-23-2014
they define an obtuse angle, and said guide element comprises at least one support element for performing the rotation that contacts the sections of the or each lever.
According to a preferred embodiment, said button comprises at least one slot for housing the upper end of the lever.
Advantageously, said guide element comprises a hole, in which said retention element is housed in its retention position.
The retention device according to the present invention has at least the following advantages:
-Provides an economic advantage for its manufacture and assembly, since it requires a smaller number of components, as the retention element and the lever or 15 levers are integrated into a single component;
-Support impacts better, since the efforts associated with impacts are transferred directly to the seat structure;
20 -It is valid for all types of vehicle seats;
- It does not represent any appreciable change for the users, since the actuation of the button is carried out in the same way as at present. 25 Brief description of the drawings
For a better understanding of how much has been exposed, some drawings are attached in which, schematically and only by way of non-limiting example, a practical case of realization is represented.

Figure 5 is a perspective view of the detail of the lower part of the retention device according to the present invention in its release position. 10 Description of a preferred embodiment
In figure 1 a headrest 3 is shown comprising a pair of fixing rods 2, one of which is housed inside a retention device of
According to the present invention.
As can be seen in this figure, the fixing rods 2 comprise grooves 12, which will serve to fix the height of the headrest 3.
20 The retention device according to the present invention comprises a guide element 1 inside which a fixing rod 2 of the headrest 3 and a retention element 4 movable between a retention position (shown in Figure 4) are housed, in which the displacement of said fixing rod 2 with respect to said guide element 1, and a release position (shown in Figure 5), in which it allows the
25 displacement of said fixing rod 2 with respect to said guide element 1.
In addition, the retention device according to the present invention comprises a button 5 for moving said retention element 4 from said retention position to said release position, at least one lever 6, two in the case of the embodiment
30 represented, linked with said button 5 which transfers the movement of said button 5 to the retaining element 4; and an elastic element 7, which presses said lever 6 towards the retention position of said retention element 4.
In order to place the retention element 4 in the retention position, the guide element 1 comprises a hole 10, as can be seen in the figures.

In accordance with the present invention, the retaining element 4 and the levers 6 are in one piece. According to the preferred embodiment shown, a U-shaped rod 8 defines the retention element 4 and the levers 6, so that the bottom of the U is the retention element 4 and the arms of the U are the levers 6.
5
Each lever 6 is preferably formed by two sections defining an obtuse angle, as can be seen in the figures, and at least one support element 11 for performing the rotation that contacts the sections of the or each lever.
10 The upper part of said levers 6 are housed in two slots 9 provided in the button 5, as can be seen better in Figure 3.
The operation of the retention device according to the present invention is as follows:
15 The guide elements 1 are placed in the upper part of the back of a vehicle seat, and the fixing rods 2 are housed inside said guide elements 1.
In this position, the retaining element 4 is housed inside the slots 12 of 20 said fixing rod 2, blocking the movement of the headrest 3.
To modify the height of said headrest 3 with respect to the upper part of the seat back, the user must press the button 5 horizontally. When the button 5 is pressed, the upper end of the levers 6, housed in the slots 9, will move in
Consequently, causing said retention element 4 to move from its retention position to its release position.
This movement is achieved thanks to the rotation of the rod 8 (formed by the levers 6 and the retention element 4), with respect to the pivot point of the support element 11.
30 In this position, the retaining element 4 is outside said notch 12, and will allow the movement of the fixing rod 2 with respect to said guide element 1.
When the headrest 3 has been placed in the desired position, it should simply be
35 release the button, and due to the action of the elastic element 7 on the rod 8, the retention element 4 will return to its retention position.
