THE GENERAL DATA

We always aspire to equip the workplace. That there was all near at hand, good illumination and that is important, a convenient armchair. And if a workplace – the car and in it it is necessary to spend time most part? As the problem in this case dares: whether conveniently to us to sit in our cars and what should be our armchair?

So, a question the first: correctness of landing is how much important?

On early models of domestic cars established the seats, absolutely not considering that factor that the person belongs to the class позвоночных. Meanwhile the automobile armchair is, as a matter of fact, a workplace: each driver, even the nonprofessional, spends in it the tenth part of the life. The backbone tests the greatest loadings in position sitting. On lumbar department the weight literally all body (even as it will not seem strange, those parts that below a belt) thus falls. Not casually, for example, after traumas of a backbone to the patient allow to stand, lie, but forbid to sit.

The backbone has a number of physiological bends: a cervical deflection forward (cervical лордоз), chest горбик back (chest кифоз), lumbar лордоз and крестцовый кифоз. Sideways the backbone reminds Latin letter S or, even, more precisely, a dollar sign – $. The vertical line here shows a weight vector, and on crossing of this vector there are the critical knots bearing the maximum loading.

As the backbone has physiological bends, the seat should these bends "indulge". The armchair back at level of shovels should be as though ruined. The lumbar department, on the contrary, needs to be propped up a small pillow. It is desirable, if it also surround a trunk, providing support to its lateral surfaces and interfering with moving to time of bends.

Question of the second: how to check up correctness of landing?

When you sit down in an armchair, each part of your body should lay down as though in a case. A head (or a neck) – on the cervical platen, a back – in back deepening, a waist – on a lumbar pillow; hips thus do not slip forward. The body weight should not fall on any its one part. It is natural, when the car will get under way from a place, you do not remain in this pose, and hardly will move forward. But on a line when it is not necessary to twirl by a head, it is possible to dare to lean back in an armchair and, holding a wheel a few to have a rest.

Question the third: what should be an automobile armchair?

The good automobile armchair should have an adjustable lumbar pillow, adjustable curvature of a back and, of course, a headrest under a neck. Last serves for prevention хлыстовой traumas (at blow in the car behind) and for maintenance cervical лордоза; even if the headrest is not present by the car – it is necessary to buy and put it. Pay attention to lateral platens on a back and a pillow, providing a lateral emphasis, and also the forward platen interfering "slipping" of the driver.

Separately I wish to tell about a seat pillow on which we sit. It necessarily should be rigid. German cars are famous for it: like an armchair under you as wooden and to sit conveniently. There is even an expression – "in German a rigid seat". The American cars, on the contrary, are equipped with excessively soft pillows of armchairs; besides, often forward seats in them are executed in the form of one "bench" that does not give a sufficient support to the case. Sometimes that part of a pillow that is under hips, has adjustment on height, and that that is closer to knees, – on length. At "adjustment under itself" on all these adjustments should be guided, of course, by criterion of convenience. In the good car, besides armchair adjustment, there is a steering wheel adjustment. People after all all different growth: the high will make a seat more low (not to fight a head about a ceiling), and the person of small growth or the woman – above. And if the seat can be lifted-lowered, also a wheel too it is necessary to regulate upwards-downwards.

Some councils to the driver who gets tired on the workplace

Any driver, especially at the wheel "трясучего" the car, should is not more rare, than time at two o'clock, to have a rest – to stop, leave the car, to do some exercises. Well also to hang for a while on a roadside tree on hands, or – if the car cargo – on a body side. It is useful to carry special "an industrial belt" – an original semicorset from a dense synthetic material with strengthening inserts in the field of a waist. Such belt unloads a back and insures against superfluous loading on vertebras. Well and the main thing – watch landing. Even if you have got used to sit in another way, try to put nevertheless under a waist a pillow – and to you it becomes obligatory more conveniently.
