Description

The The invention relates to a headrest for motor vehicle seats with at least two rod-shaped Holding elements and a spanned by the holding elements network, wherein the separately arranged holding elements in each case via at least a connection point with the motor vehicle seat are connected.

It is already a headrest for motor vehicle seats from the DE 27 14 796 A1 known. It shows net headrests for a seat of a motor vehicle, which consist of a seat-mounted frame and a grid attached to the frame. The frame is designed to be open on at least one side, wherein the network is held in the edge region of the open side of the frame under high tension compared to the remaining net area. According to embodiment according to 2 In this case, the frame can also be formed from two rod-shaped frame parts which are attached to the motor vehicle seat.

The DE 28 39 015 A1 shows a headrest for vehicle seats with a surface support, which is formed from a support frame and has openings, wherein the surface support consists of a material with a high elastic modulus and has a considerable bending stiffness. The DE 28 39 015 A1 also states that the surface support is formed as a wire mesh or wire mesh or as a wire mesh or a chemical material. The support frame is connected via two spars or a spar with the vehicle seat.

The DE 22 04 627 A1 shows a headrest with an adaptive, but substantially inelastic support surface, which pivots upon impact of the head with a corresponding expenditure of energy.

The DE 196 22 146 A1 shows a headrest, which is formed from a retractable in a back frame with a net enclosed therein. The frame is connected via two legs slidably connected to the vehicle seat.

Of the Invention is based on the object, a headrest such train and arrange that a discreet, the driver's field of vision only marginally debilitating Use guaranteed is.

Is solved the task in conjunction with the features of the preamble of Claim 1 according to the invention thereby, that at least one over a connection point with the motor vehicle seat connected third Holding element is provided and between the third holding element and the second holding element, the network or a network part spanned is. This ensures that the obstructive parts of the Headrest, So the holding elements, essentially vertical, so that they related to the lateral rotation of the head no steady To form a visual obstacle. By the rod-shaped, essentially vertical extending training of the holding part, the driver can be independent of his head height Stop by the holding element. In addition to this safety Aspect of the driver's extended field of view is the feeling of space of the vehicle occupants the transparency of the headrests elevated. In addition, the lateral extent of the headrest is extended.

This lateral area serves as a so-called headrest ear in support of the Head in a resting position.

A additional possibility is according to a further development, that at least one over a connection point connected to the motor vehicle seat fourth Holding element is provided and between the fourth holding element and the first holding member the network or another network part is stretched. The extension formed on both sides the headrest guaranteed a symmetrical shape that is both a right and a left Rest position of the head allows.

Further it is advantageous that the holding element perpendicular to its central axis pivotable and lockable in any position. The pivoting of the holding element is ensured perpendicular to its central axis optimal adjustment of the headrest including the Page ranges in terms of absolute tilt forward and to the rear and in terms of the inclination between the headrest and Headrest ear.

Advantageous it is also this that the holding element and / or the network elastic and / or is plastically formed. The elastic-plastic training guaranteed an optimal impact protection of the head. Here is the plastic Deformation share necessary for some of the kinetic energy is transformed into plastic deformation work. A purely elastic Deformation would the head after the necessary delay again around the same Accelerate amount in the opposite direction.

According to a preferred embodiment of the solution according to the invention is finally provided that the holding element parallel to its with Telachse is slidably and / or telescopically fixed in any position. Thus, a height adjustment of the headrest and thus an optimal adjustment for a rest position is guaranteed.

in the Connection with the construction and arrangement according to the invention It is advantageous that the holding element, the locking elements has switching control units. The determination of the retaining element is also by twisting around its central axis or by one axial impressions to reach the driver's seat.

Further Advantages and details of the invention are in the claims and explained in the description and shown.

A headrest shown in the figure 1 a motor vehicle seat 2 essentially has four rod-shaped holding elements 3.1 to 3.4 on, in the space between a network 4 or a network part 4.1 . 4.2 is provided. The first holding element 3.1 and the second holding element 3.2 are here in the middle between the third holding element 3.3 and the fourth holding element 3.4 arranged and take the net between them 4 on. According to 1 to the right side is the third holding element 3.3 provided, which together with the second holding element 3.2 the power supply 4.2 spans. Accordingly, on the left outside of the fourth holding element 3.4 provided, which together with the holding element 3.1 the power supply 4.1 spans.

The respective holding element 3.1 to 3.4 is over a connection point 5 with the vehicle seat 2 connected. This connection allows a pivoting of the holding elements 3.1 to 3.4 perpendicular to their partially represented central axes 3.5 . 3.6 forward and sideways towards. Thus, the network can 4 or the network parts 4.1 . 4.2 be set according to a desired driving position or rest position. The network parts 4.1 . 4.2 form together with the third and fourth retaining element 3.3 . 3.4 so-called headrest ears. In addition to the pivoting of the retaining elements 3.1 to 3.4 perpendicular to its central axis 3.5 . 3.6 is also a setting parallel to the central axis 3.5 . 3.6 , ie provided in height.

The network 4 or the network parts 4.1 . 4.2 and the holding elements 3.1 to 3.4 are elastic or elastic-plastic.
