DETAILED DESCRIPTION OF THE INVENTION
An example of the use of the present invention will be described. 1 to 6, the shock absorber in this example is provided between the bottom of the body and the sheet. In this example, the shock absorber and the sheet are connected via a spacer plate material (shocker plate with impact absorbing material or absorbing means) and / or a second absorbing means for concealing the opening of the shock absorber. Therefore, when a shock is applied to the vehicle body (vehicle), in the case of a monocoque body, the shock absorption by the monocoque body and the deformation of the shock absorber itself and / or the bulge of the shock absorber and the shock absorber The impact in the front-rear direction and / or the left-right direction is absorbed by a change in the gap. If necessary, the vertical impact of the shock absorber is utilized to absorb the vertical impact. For example, a structure that absorbs an impact in the vertical direction through elasticity such as the ban force of the shock absorber is conceivable. Of course, it is possible to absorb impacts in at least one direction through individual deformations, or to absorb impacts in all directions through comprehensive deformations. This shock absorption can be comprehensively absorbed by the deformation (plastic and / or shape deformation) of the substantially annular connecting link piece constituting the link piece group and the rod-like connecting link piece and / or the characteristics of the steel. It is. In particular, it is desirable to provide a seat impact absorbing structure that can be employed in a structure in which the seat belt is fixed to the seat (in order to ensure the safety of the seat itself and simplify the use). Further, by utilizing the structure and / or elasticity of this shock absorber, it is possible to absorb the distortion of the floor and / or the seat structure, and to set the seat accurately and in a predetermined position, and to maintain these functions, or It is possible to use floors and / or seats and various parts that could not be used through adjustment, eliminating the occurrence of defective products, facilitating installation, speeding, labor saving (labor saving), Or there are practical benefits that help to reduce costs, use resources effectively, maintain the environment, and so on. It should be noted that other base materials such as reclining, sheet movement, etc. can be maintained, and as in the previous case, reclining and various parts that could not be used in the past can be used, eliminating the occurrence of defective products, In addition, there are practical benefits useful for ease of installation, speeding, labor saving (labor saving), cost reduction, effective use of resources, environmental maintenance, and the like.
[0028]
And the distributed shock absorption by the curved surface shape of the substantially annular connecting link piece provided in the shock absorbing material and / or the second absorbing means and / or the substantially linear type shock absorption by the directionality of the rod-like connecting link piece, and the link The shock can be absorbed in a shock-proof and reliable manner through a combination with a space (gap) formed between the groups. Therefore, absorption that is kind to humans and absorption that is useful to weak people such as disabled vehicles and sick people is possible. There may be individual relationships between these variations and characteristics.
[0029]
In addition, when the shock absorbing structure is attached to the seat with bolts and nuts, the shock absorbing material or the seat can be tightened from any direction in consideration of the vehicle type or the mounting situation. Further, for example, even when the shock absorbing structure is attached to the seat, it can be inserted from the window frame, so that the assembly can be facilitated, simplified, or reduced in cost. When the shock absorbing material is damaged, the bolt and / or nut are removed and replaced after removing the seat from the bottom. After that, it is as described above. By forming an outer peripheral frame around the opening of the shock absorber, it is possible to improve the strength of the spacer plate material and / or the shock absorber and to withstand the upward impact of the spacer plate material or the like. There are practical benefits such as the stability of the shape of the plate material and the ability to withstand the load on the sheet.
[0030]
Another example of the use of the present invention will be described. 7 to 11 will be described. The shock absorber in this example is provided between the bottom of the body and the sheet. In this example, the shock absorber and the sheet are connected via a spacer plate material (and / or shock absorber) and / or second absorber below the first absorber provided on the shock absorber. . Therefore, when there is an impact on the vehicle body (vehicle), in the case of a monocoque body, the first absorption means and the deformation of the second absorption means itself and / or the bulging portion of the shock absorber and the shock absorption are also accompanied. The impact in the front-rear direction and / or the left-right direction is absorbed by changes in the gap with the material. If necessary, the vertical impact of the spacer plate / first absorbing means and / or impact absorber is utilized to absorb the impact in the vertical direction. Of course, it is possible to absorb impacts in at least one direction through individual deformations, or to absorb impacts in all directions through comprehensive deformations. This shock absorption can be comprehensively absorbed by plastic (and / or form) deformation of the substantially annular connecting link piece constituting the link piece group and the rod-like connecting link piece and / or the characteristics of the ban steel material. .
[0031]
In this example, as shown in FIGS. 9 and 10, a combination structure of the upper surface of the shock absorber and the spacer plate material or the bolt and nut can be used. Structure) shock absorbing structure is completed. Fig. 9 shows an example in which the shock absorbing structure is attached to the seat with a bolt and a nut. (A) is an example of fixing the bolt to the shock absorbing structure, and (B) is an example of fixing the bolt to the seat. Is shown. FIG. 10 shows an example of the shock absorbing structure described in relation to the shock absorber and spacer plate material. (A) shows an example in which the spacer plate material is attached and fixed (fixed) to the shock absorber via a bolt. In addition, (b) shows an example in which a spacer plate is attached and supported to the shock absorber through a bolt, and a gap is provided between the shock absorber and the spacer plate. (C) shows an example in which the shock absorber is fitted with a bolt. (D) shows an example in which the spacer plate material is reversely supported by a shock absorber through a bolt, and (e) shows another example of the above (b). Each of these examples is part of the conforming structure shown in FIG. 12 and FIG. 13, and the manufacturing side of the manufacturer (simplification, simplification, cost reduction, efficiency improvement, etc.) of the manufacturer or the usage side of the purchaser ( (Ride comfort, safety, cushioning, shock absorption) etc. Other structures, handling, movement or absorption at the time of impact, etc. are the same as in the above example.
[0032]
14 to 17, the movements from primary shock absorption (primary pump) to tertiary shock absorption (tertiary pump) will be described. In one example, the primary shock absorption is achieved by deformation of the upper link piece group (primary absorption means). This change is indicated by an imaginary line (same below). Secondary shock absorption is achieved by deformation of the bulging portion. Further, tertiary shock absorption is achieved by deformation of the link piece group (secondary absorbing means) on the side surface. For the deformation of the bulging portion, it is safe to maintain a deformed shape such as a stoker via the stopping means. In this shock absorption, the deformation distance (deflection length) and the ban constant are correlated. For example, if the deflation length (L) is large, the ban constant is small and sufficient shock absorption is possible. Then, a mechanism suitable for the vehicle or use is employed by utilizing a combination of the primary shock absorption to the tertiary shock absorption and / or the shift of the spacer plate material (see FIG. 13). In addition, FIG. 17 has shown the relationship between a load and bending, and showed the said primary impact absorption-tertiary impact absorption as an example.
