Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a seat for vehicles, airplanes, etc. according to the preamble of claim 1.

[0002]

2. Description of the Prior Art Seats installed in vehicles or airplanes, which are often exposed to alternating curves or high curve passing speeds, provide good support for passengers transported on these seats. It is expected.

German Patent No. 34 17 61
From 6 specification, a vehicle seat with a seat and a back is clear, the seat and the back having a fixed seat or back support. The seat support and the back support project beyond the seat upholstery surface or the backrest upholstery surface, which precludes the seating of the passenger, which is basically done transversely to the vehicle seat.

[0004]

SUMMARY OF THE INVENTION Therefore, the object of the present invention is to provide a seat for vehicles, airplanes, etc., in which the passengers who use the seat each time are ideally supported during lateral acceleration. It is also necessary to take safety measures so that the above passengers can easily reach this seat.

[0005]

This problem is solved according to the invention by the features of claim 1. Further developments of the invention are contained in the subclaims.

The advantages primarily achieved by the present invention are:
Thanks to the adjustable seat or backrest support of the seat or backrest, the seats equipped with these not only provide good lateral retention for the respective passenger, but also It is also possible to exercise in two states, and in this state, it is easy for this passenger to sit down. The seat supports or back supports are formed such that the seat supports or back supports are adaptable to different heights of passengers. The adjustability of the position of the backrest support is pivotable via a swivel axis extending in the longitudinal direction of the backrest, and furthermore in hinges spaced in the longitudinal direction of the swivel axis. If supported, it can be easily achieved.
The squeezing deformation in the backrest and the depressions in the backrest support contribute to ensuring that the backrest support is properly movable around this pivot axis. It is also advantageous to orient the pivot axis of the seat support horizontally and to provide a comparatively small distance to the laterally extending border in front of the seat. In short, the arrangement of the adjusting levers contributes to the structural simplification and the ergonomic operability of the seat with respect to the seat longitudinal position adjustment in the seat.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT An embodiment of the present invention is shown in the drawings and will now be described in detail. A seat 1, suitable for installation in a vehicle, an airplane, etc., is longitudinally slidably mounted on a suitable bottom of the vehicle body-not shown. The seat 1 is formed by a seat portion 2 and a backrest portion 3, and the seat portion and the backrest portion are provided at an angle to each other. Seating supports 7, 8 or backrest supports 9, 10 are provided on the long side surfaces 5, 6 of the seat 1 or seat 2 and backrest 3 on both sides of the central longitudinal surface 4. The seat supports 7, 8 and the backrest supports 9, 10 provide lateral support for passengers who use this seat, for example when passing through curves with alternating and correspondingly high lateral acceleration values. give. The seat supports 7, 8 and the backrest supports 9, 10 are formed adjustable and independent of each other. For this purpose, these seat supports 7, 8 are formed in such a way that their position can be adjusted via a pivot axis 11 extending transversely to the seat 1.
These seat supports 7, 8 are movable from the first embedded state Sv to the second extended state Sa and vice versa from the extended state to the embedded state.
The turning axis 11 is provided at a relatively small distance from the front boundary portion 12 of the seat 1 or the seat portion 2 and is aligned in a substantially horizontal direction. The seat part supports 7 and 8 formed in these plate shapes have the seat cushion height S of the seat part 2 in the embedded state Sv.
kh, i.e., these seat supports do not project beyond the seat upholstery surface 13 of said seat, so that they are stowed.

The backrest supports 9, 10 are positionally adjustable in the longitudinal direction BB of the backrest 3 and by swivel axes 14, 15 which are oriented along the long side faces 16, 17 of these backrest supports. . For this purpose, these backrest supports 9, 10 are supported at a distance from one another on hinges 18, 19 and 20, 21 which are provided along pivot axes 14, 15.
These backrest supports 9, 10 are positionable between a first flat state Sf and a second right-angled state Sw.

The backrest 3 comprises hinges 18, 19 and 2
In the long side surfaces 16 and 17 between 0 and 21, there are diaphragm deformation portions 22 and 23 that are separated from the turning axis lines 14 and 15. And these back support 9, 10
Between the hinges 18, 19 and 20, 21 are provided with recesses 24, 25 which have a convex profile with respect to the long side surfaces 16, 17 of the backrest 3.

The seat supports 7, 8 and the backrest supports 9, 10 can be manually adjusted by any suitable device. However, it is also possible to position these seat and back supports electrically, hydraulically or pneumatically.

The seat 2 is provided with a recess 26 in the central longitudinal surface 4 of the seat supports 7 and 8 which is open towards the front boundary 12. The recess 26 serves for accommodating a position adjusting lever 27, which allows, for example, adjustment of the longitudinal position of the seat.
It can be performed indoors. This position adjustment lever 27
Has a grip 28 and is embedded in the entire range,
It is stored in the recess 26.
