Description

The present invention relates to a seat pad structure, and more particularly to a seat back pad structure for a seat back.

(Prior Art) Conventionally, for example, in a seat 1 including a seat cushion 2 and a seat back 3 of an automobile, particularly in a seat back pad 4 of the seat back 3, the entire pad 4 is made of a soft urethane foam having the same hardness. However, the side pad portion 5 has been enlarged in recent years to express the luxury of the seat, but wrinkles and the like occur when the skin material is wrapped, which requires a lot of work for the binding work. Therefore, the side pad portion 5 is integrally molded with a urethane foam having a hardness higher than that of the urethane foam of the main seat portion 6 to prevent wrinkles from being generated in the skin material during the packing operation, and the side pad portion having a different hardness. Seat back 3 by 5
Had a hold property.

(Problems to be solved) However, although the side pad portion 5 is integrally formed of urethane foam having a different hardness, the workability of holding the skin material and the holding property are improved, but when the occupant is seated, The left and right scapula parts hit the hard side pad parts 5, and there was a problem that the riding comfort was deteriorated.

The present invention has been made to solve the above-mentioned conventional problems, and an object of the present invention is to provide a seat back pad structure of a seat back having good riding comfort.

(Means for Solving the Problems) In order to solve the above technical problems, the present invention provides a seat back pad integrally formed with a main seat portion and side pad portions formed in a raised shape on the left and right sides of the main seat portion. , The main seat portion is a soft urethane foam material, and the left and right side pad portions are integrally foam-molded with a urethane foam material that is harder than the soft urethane foam material, and the left and right side pad portions of the passenger are The pad structure of the seat has a structure in which a recess is formed in a predetermined range above and below the shoulder line, and a soft pad element having a pad surface that follows the raised surface of the side pad is fitted in the recess.

(Operation) With the above configuration, the soft pad element acts to protect the shoulder of the occupant.

(Embodiment) Next, one embodiment of the present invention will be described with reference to the drawings. In the figure, 11 is a seat back pad, and the seat back pad 11 is a main seat portion 12 on which an occupant sits, and this main seat. The raised side pad portions 13 are integrally formed on the left and right sides of the portion 12, and the main seat portion 12 and the side pad portions 13 are made of a soft urethane foam material in the same manner as in the conventional case. , The side pad portion 13 is the main seat portion 12
It is integrally molded with a urethane foam material that is harder than the soft urethane foam material. The left and right side pad portions 13 of the seat back pad 11 formed as described above are configured as follows.

In the left and right side pad portions 13, when an occupant having a normal physique is seated, the shoulder line Lb of a person having a large physique and the shoulder portion of a person having a small physique centering on the line L of the shoulder of the occupant. In the range including the line Ls, for example, a substantially rectangular recess 14 is provided, and a pad element 15 is fitted and fixed in the recess 14.

The pad element 15 is made of, for example, a soft urethane foam material similar to that of the main seat portion 12. The pad element 15 can be fitted into the pull-out concave portion 14 and is formed in a slightly larger substantially square columnar shape, which is the outside thereof. The pad surface 16 is the side pad portion 1
3 is formed on the pad surface 16 following the raised surface 13a. The pad element 15 formed in this manner is used as the extraction recess 1
4 is elastically fitted and fixed, and the surface 16 is fixed so as to substantially follow the raised surface 13a of the side pad portion 13.
The seat back pad 11 thus formed is covered with a skin material to form a seat back.

As described above, in the seat back pad 11 of this embodiment, the main seat portion 12 is made of a soft urethane foam material, and the left and right side pad portions 13 are made of a urethane foam material harder than the soft urethane foam material of the main seat portion 12. With foam molding integrally with,
The left and right side pad portions 13 center around the shoulder line L of an occupant of a normal physique, and have a substantially square-shaped recess 14 in a range including the shoulder line Lb of a large physique and the shoulder line Ls of a small physique. Is recessed, and this recessed recess 1
Since the soft pad element 15 having the pad surface 16 that imitates the raised surface 13a of the side pad portion 13 is fitted in the position 4 in FIG. Since the shoulder portion is protected by the pad element 15, the seating property similar to that of the seat back pad, which is substantially soft as a whole, can be obtained, and the riding comfort is improved. In addition, it is possible to maintain the wrapping work that does not cause wrinkles or the like on the skin material, and the holding property is not lost.

(Effects of the Invention) With the above-described configuration, the present invention can improve the riding comfort, can maintain the wrapping work without wrinkles, etc. on the surface material, and can hold Never lose.
