  In contrast to the conventional seat grip as described above, the inventor of the present application has an insertion grip that can be gripped by inserting a finger, and a spherical grip that is provided on the upper portion of the insertion grip and is formed in a spherical shape and can be gripped by a palm. Devised a new seat grip equipped with

  In this new seat grip, the lower part is an insertion grip, so the insertion grip can be gripped smoothly and accurately from below, and when the passenger sitting in the rear seat stands up, Can support the body firmly. In addition, since the upper part is a spherical grip, it is possible to smoothly grip the spherical grip from above or attach a hand to the spherical grip smoothly. You can support your body firmly by putting your hand on. Furthermore, because the spherical grip has a spherical outer surface and no directionality, it can be applied to various seats with different seat grip attachment angles even when the backrest is greatly reclined. However, when the passenger moves through the passage, it is possible to satisfactorily grip the spherical grip or attach a hand to the spherical grip.

  By the way, when realizing the above-mentioned new seat grip, the inventor of the present application mainly grips the insertion grip when the passenger sitting in the rear seat stands up, so it can be gripped firmly. While it is desirable to be able to make it as rigid as possible, the spherical grip is a gentle fit to the palm of the hand, mainly because the passengers grip and attach hands while moving down the aisle. Thus, as a result of earnest research, it was newly found that it is desirable to have a certain degree of softness.

  The present invention has been made in view of the above circumstances, and an insertion grip that can be gripped by inserting a finger, and a spherical grip that is formed in a spherical shape and is provided on the upper portion of the insertion grip and can be grasped by a palm. It is an object of the present invention to provide a novel seat grip that can be firmly configured as an insertion grip and to have a certain degree of softness in a spherical grip.

The main means taken by the present invention to solve the above problems are as follows:
"A seat grip on the upper part of the backrest of a vehicle seat,
An insertion grip that allows the user to insert and grasp the finger;
A seat grip comprising a spherical grip formed by a member that is more flexible than the insertion grip and attached to an upper portion of the insertion grip.
It is.

  If the entire seat grip including the insertion grip and the spherical grip is formed of a hard material, the insertion grip can be obtained while the desired softness of the spherical grip cannot be obtained. Further, if the entire seat grip is made of a soft material, the softness of the spherical grip can be obtained, while the desired firmness of the insertion grip cannot be obtained. Therefore, in the above configuration, the insertion grip and the spherical grip are individually formed, and the spherical grip is formed of a material softer than the insertion grip. Thereby, while being able to comprise a penetration grip firmly, a certain amount of softness can be given to a spherical grip.

In the means described above,
“The spherical grip is composed of a spherical member having an outer fitting portion that externally fits the insertion grip and a slit that is provided below the outer fitting portion and that allows the outer fitting portion to expand. Seat grip featuring
It is good.

  In the above configuration, since the external fitting portion of the spherical grip is externally fitted to the insertion grip, the spherical grip can be firmly attached to the insertion grip so that there is no rattling. Further, since the outer fitting portion can be expanded by the slit, the spherical grip can be smoothly attached to the insertion grip. In addition, since the slit is provided below the outer fitting portion, the slit is not exposed to the side surface or the upper surface of the spherical grip when the spherical grip is attached to the upper portion of the insertion grip. Therefore, the slit does not impair the aesthetic appearance, and even when the spherical grip is gripped, it is difficult to touch the slit portion, and the fit of the hand gripping the spherical grip is not significantly impaired.

In the means described above,
“A groove is provided on each side of the slit of the spherical member,
The seat grip, wherein the outer fitting portion is fixed so as not to expand by a fixing cap having a fitting portion fitted in each groove portion.
It is good.

  For example, a spherical grip externally fitted to the insertion grip may be directly fixed to the insertion grip by a set screw. However, since the spherical grip is a flexible member, there is a possibility that the fixation by the set screw may become fragile. . In addition, the set screw is exposed on the outer surface of the spherical grip, and there is a risk of hindering the fit when gripped by hand.

  On the other hand, in the above configuration, the fitting portion of the fixing cap is fitted into the groove portions provided on both side portions of the slit, thereby restricting the expansion of the outer fitting portion, and the spherical shape attached to the insertion grip. Make sure that the grip does not come off. Therefore, the spherical grip can be firmly fixed to the insertion grip. In addition, the fixed cap is attached to the slit portion on the lower surface of the spherical member and is not greatly exposed on the side surface or upper surface of the spherical grip. Therefore, depending on the fixed cap, when the spherical grip is gripped by hand, A feeling of fitting is not greatly impaired.

  As described above, according to the present invention, the insertion grip that can be gripped by inserting a finger, and the spherical grip that is formed in a spherical shape and that is provided on the top of the insertion grip and that can be gripped by the palm of the hand are provided. In the seat grip, the insertion grip can be firmly configured, and the spherical grip can have a certain degree of softness.
