It is parallel and coplanar with transverse reference line L6 to positioning light beam L4 and the second located lateral light beam L5.
As shown in Figure 3 and Figure 4, the invention also discloses the automotive seats of the above-mentioned car seat headrest dimension measuring device of application
Chair headrest dimension measurement method, is implemented based on above-mentioned car seat headrest dimension measuring device, including：
Its backrest shaft 61 and its seating reference point, that is, automobile R in the drawing data of automotive seat 6 are tested Step 1: obtaining
Relative position between point, and pass through locating rod mobile mechanism 1032 and adjust between shaft locating rod 1031 and R dot center bar 102
Relative position so that the relative position adjusted is identical with the relative position in drawing data.
Step 2: the relative position of adjustment pedestal 101 and tested automotive seat 6, enables shaft locating rod 1031 and tested vapour
The backrest shaft 61 of vehicle seats 6 it is coaxial and, enable first longitudinal direction positioning light beam L2 that first longitudinal direction rangefinder 2 sent out and/or
The second longitudinal direction positioning light beam L3 that second longitudinal direction rangefinder 3 is sent out is fallen on the left and right Axisymmetric Distributed Line of tested automotive seat 6, with
So that the longitudinal datum line L1 and transverse reference line L6 and the left and right Axisymmetric Distributed Line of tested automotive seat 6 of rack 1 are coplanar, and cause
The crossing point of axes of R dot center bar 102 and trunk bar 104 is located at the seating reference point of tested automotive seat 6 at i.e. automobile R points；
Wherein, usually by the left and right Axisymmetric Distributed Line of tested automotive seat 6 label on the surface of tested automotive seat 6, in order to first
Longitudinal register light beam L2 and/or second longitudinal direction rangefinder 3 are positioned, and in order to ensure the accuracy of measurement, what this was marked
Left and right Axisymmetric Distributed Line is usually what is be determined with being tested the skeleton of automotive seat 6, because the Soft Roll part of automotive seat is general
It is difficult to symmetrical.
Step 3: obtaining the angle of body being tested in the drawing data of automotive seat 6, and pass through and rotate trunk bar 104 so that
The angle in 104 opposed vertical direction of trunk bar is identical with angle of body, at this point, trunk bar 104 is parallel to the body of tested automotive seat 6
Main line.
Step 4: by the way that by first longitudinal direction rangefinder 2 and second longitudinal direction rangefinder 3, blade 106 moves along longitudinal direction respectively, it will
Transversely blade 107 moves the first lateral lateral rangefinder 5 of rangefinder 4 and second respectively, determines the visible light-seeking light beam of four beams
The boundary of the tested automotive seat 6 in position, to measure the headrest dimension data of tested automotive seat 6.
In step 4, be tested automotive seat 6 headrest dimension data include height of headrest, headrest width, pillow highly with
And it is any one or more in the spacing between headrest and backrest, concrete mode is as follows：
When measuring height of headrest, the headrest of tested automotive seat 6 is adjusted to highest lock position, mobile first longitudinal direction is surveyed
Distance meter 2 so that first longitudinal direction positions the tangential of light beam L2 and headrest, at this point, the distance number that first longitudinal direction rangefinder 2 measures
According to the height of headrest for being tested automotive seat 6.
When measuring headrest width, the lateral rangefinder 5 of mobile the 2, first lateral rangefinder 4 and second of first longitudinal direction rangefinder,
So that the tangential of first longitudinal direction positioning light beam L2 and headrest, the first located lateral light beam L4 and the second located lateral light beam L5
It is tangent with the both sides of headrest respectively, at this point, the range data that the first lateral lateral rangefinder 5 of rangefinder 4 and second measures respectively
The headrest width of as tested automotive seat 6, that is, the left and right width rested the head on, wherein, the first located lateral light beam L4 and second is horizontal
It is by measurement car seat headrest size to the distance between plane where positioning light beam L5 and first longitudinal direction positioning light beam L2
It as defined in standard, is provided according to existing GB 15083, GB 11550, which is 65mm.
When measuring pillow height, mobile first longitudinal direction rangefinder 2 and second longitudinal direction rangefinder 3 so that first longitudinal direction positions
The tangential of light beam L2 and headrest, second longitudinal direction positions light beam L3 and the bottom of headrest is tangent, at this point, first longitudinal direction rangefinder
2 and the difference of range data that measures respectively of second longitudinal direction rangefinder 3 be the pillow of tested automotive seat 6 highly.
When measuring the spacing between headrest and backrest, the headrest of tested automotive seat 6 is adjusted to minimum lock position, point
Move second longitudinal direction rangefinder 3 twice so that second longitudinal direction position light beam L3 when this is moved twice respectively with the bottom of headrest
With the backrest tangential of tested automotive seat 6, at this point, second longitudinal direction rangefinder 3 measured respectively when this is moved twice away from
Difference from data is the spacing between the headrest and backrest of tested automotive seat 6.
Wherein, the adjutage 105 of car seat headrest dimension measuring device makes between trunk bar 104 and longitudinal blade 106
Effect there are gap is：Since the straight line extended since automobile R points along the torso-line direction of tested automotive seat 6 necessarily passes through
Some position of tested automotive seat 6 is crossed, the position as rested the head on, between headrest and backrest, therefore, if being not provided with semi-girder
105, and be made of one directly by trunk bar 104 with longitudinal blade 106, then when measuring, because of the behaviour of step 2 and step 3
Make, rack 1 can cause longitudinal blade 106 to be interfered with tested automotive seat 6, cause nothing very close to tested automotive seat 6
